Best Practices In Load And Stress Testing Cmg Seminar[1]Munirathnam Naidu
The document discusses best practices for performance testing. It provides an overview of the typical performance testing process, including defining goals, planning tests, scripting tests, executing tests, analyzing results, and delivering findings. It also discusses considerations for choosing testing tools and resources as well as common pitfalls to avoid, such as not testing, poor planning, relying on customers to find issues, using the wrong tools, and failing to properly isolate variables.
With every passing day, organizations are becoming more and more mindful about the performance of their Software Products. However, most of them still on look-out for the basics of Performance Engineering.
According to a recent study by Gartner, fixing performance defects near the end of the development cycle costs 50 to 100 times more than the cost required for fixing it during the early phase of development. Hence, if a product suffers from serious performance issues it can be completely scrapped.
Performance Engineering ensures that your application is performing as per expectations and the software is tested and tuned to meet specified or even the unstated performance requirements.
We present you with a webcast on Performance Engineering Basics that would walk you through the elements and process of performance engineering, and also offers a methodical process for the same.
It also offers details on a load testing tool, and describes how best to utilize it.

This allows identification of costly transactions, features, user behavior, and tenants to better optimize spending.
Don't Lose Your Viewers: Keep Their Attention With High Performance StreamingCompuware APM
Significant effort and investment go into producing great online advertisements, music videos, and trailers for blockbuster movies. If the video stream is not available, you end up with “dead air.” If the stream rebuffers repeatedly, causing users long wait times, you’re creating poor end-user experience and, worse, possibly losing them as customers. Both outcomes are going to result in a negative impact on your brand and your revenue.
Why Server Virtualization Demands an End-user’s PerspectiveCompuware APM
Enterprises regularly refresh server platforms to harness improvements in compute capacity, power consumption and maintenance costs. In 2012, servers are more likely to be virtualized than physical, presenting new challenges in a migration project. Monitoring at a component-level won't improve performance but subjective monitoring of the end-user experience (EUE) does.
Today's Application Performance Management (APM) tools employ EUE monitoring so pre-migration baselines and post-migration SLAs are based on what matters: the subjective quality of user experience. The added benefit? APM identifies and resolves problems more quickly than component monitoring tools. This shields server migration projects from costly extensions and infrastructure overlaps by accelerating problem identification and resolution.
Join Compuware and featured guest Forrester Research, Inc. in this webcast to understand:

Measure Twice, Cut Once: 5 Best Practices For Selecting Your Cloud Service Pr...Compuware APM
So, you’ve defined your cloud strategy, developed the business plan, published your cloud application roadmap, and got buy-in from all the stakeholders. Now comes the hard part – selecting your cloud service providers and partners!
Many companies are finding out the hard way that while the cloud is a simple concept, beneath the billows lays a complex application delivery chain with many hidden dependencies and unforeseen business risks. And with the business demanding faster and faster ‘time-to-value’, you have less time to do more, often without good information. The net result is your risk of choosing the wrong cloud service provider is significant. It could even reduce or eliminate the planned business benefits and ROI.
So how can you ensure that your selection process for cloud service providers and partners is fast but well-informed, based on reliable data and mitigates the risk of hidden surprises?
Join EMA and Compuware in this webinar and discover:
• Where to find reliable, actionable data on CSP performance and availability
• What factors you should take into account that are unique to you
• Whether SLAs matter when it comes to selecting a CSP
• How to identify hidden dependencies and unforeseen risks
• How to do cost-effective, real-world performance testing of CSPs
How to Mitigate the Performance Risk of Third-party Web ComponentsCompuware APM
No website is an island. To provide rich customer experiences, websites increasingly depend on third-party components such as shopping carts, ads, customer reviews, web analytics, social networking, search engine optimization, video, and many more. Third-party components enrich your website’s functionality to drive more traffic to your site, offer interactive experiences, increase conversion, and add new functionality when it becomes available.
The problem: Your entire website can be vulnerable to degraded performance or a complete shutdown if any one of these components fails. The solution is to follow best practices in website design and monitoring to happily use third-party components while mitigating the risk of dependency.
Forrester principal analyst Mike Gualtieri and Compuware APM CTO Steve Tack to show:
• How third-party components can make your website better and why this trend will only increase.
• Why service level agreements give you a false sense of security.
• Best practices to mitigate the risks of using third-party components.
Optimizing web and mobile site performance using page speedCompuware APM
End-users’ expectations for web and mobile site performance keep rising. In a 2011 survey of 4,014 mobile web users 71% stated they expect websites to load as quickly, almost as quickly or faster on their mobile phone than on the computer they use at home – up from 58% in 2009.
With web and mobile sites your customers expect transactions that are fast and work faultlessly. Failure to deliver quality web experiences through slow or malfunctioning sites will result in lost customers and business.
Featured speakers, Bryan McQuade, Senior Software Engineer at Google and Page Speed tech lead, and Compuware APM CTO Steve Tack show:
• What end-users rising performance expectations mean for website owners and developers

The document urges companies to monitor mobile performance.
Are Your Applications Delivering What Your End-Users Expect?Compuware APM
The end user experience is a critical pillar of application performance management. It requires a global view that tracks the path of an application from data center through the Internet, and all the way to "the last mile" of delivery to the end user's computer or device.
Although a well-established discipline, traditional application performance management approaches provide highly silo'ed views of application delivery to the end user. A full picture requires breadth and depth, and a view of the full business impact.
Featured speakers, Tony Baer, Senior Analyst from independent research firm Ovum, and Compuware APM CTO Steve Tack to show:
• Why traditional monitoring doesn’t tell the full story
• The top 5 APM best practices
• How to build your APM roadmap: applying best practices and creating your performance journey
Managing Complexity Across Today’s Application Delivery Chain:Six key indicat...Compuware APM
Managing Complexity Across Today’s Application Delivery Chain:
Six key indicators for prioritizing application performance improvements
Today’s application delivery chain is harder to manage than ever. Applications ranging from mission-critical legacy systems to innovative productivity tools running on employee-owned smartphones all must be delivered flawlessly. Additionally, technologies like virtualization, the cloud and WAN optimization make managing performance even more complex. As each new application generation is deployed on top of existing assets, managing system-wide application availability and performance becomes increasingly dependent on a growing collection of incompatible tools, informal processes and multiple – often siloed – stakeholders.
This complexity is only going to grow. In this webinar, you will learn how to tame complexity and optimally manage application availability and performance.
• J.P. Garbani, of Forrester Research, highlights new research that assesses the complexity in IT operations, both now and in the future.
• Compuware’s Steve Tack details a strategic approach that will allow customers to plan and implement a coherent, structured APM framework based on the concept of an APM “Performance Journey.”
You'll learn :
• six key indicators that will reveal your APM problem areas
• how to develop a performance journey roadmap based on five core areas of APM best practices in order to manage and monitor application complexity more efficiently
• how to achieve the following goals:
• increase productivity while lowering costs
• maintain and improve service quality
• adopt new service demand quickly and efficiently
• align IT goals to meet business needs
• what the future holds for IT operations

5 Best Practices for Successful Cloud Deployments – and the Pitfalls to AvoidCompuware APM
Companies that rely on enforcing Service Level Agreements (SLAs) from their Cloud Service Providers to manage the performance of their cloud applications are increasingly discovering that they are failing to meet their business objectives. The reality is that by the time an SLA has been missed, your end users and customers have already been severely impacted, resulting in poor adoption and missed revenue opportunities.
Successful cloud deployments require real-time visibility of application performance and service level trends across the entire delivery chain – from first mile (your data center) to last mile (your users). This insures that companies are able to detect problems anywhere in the delivery chain, before end users, customers, and your business are impacted.
This webinar will provide evidence of the revenue impact of poor cloud application performance and service level management, and will present an integrated cross-domain services and application performance management strategy that will dramatically improve the business results that you achieve with Cloud Computing. The information will be of use to anyone who is responsible for the successful execution of their company’s cloud strategy, both in the line-of-business and IT.
Dennis Drogseth, Vice President, Enterprise Management Associates, Inc and Richard Stone, Compuware’s Cloud Solutions Manager talk about:
• Research results showing how and where companies are benefitting most, and conversely where they’ve had issues, or had to rethink and redirect their cloud initiatives
• Best practices to adopt – and pitfalls to avoid – that will enable you to get cloud deployments right the first time from both a process and an APM perspective

Quality Patents: Patents That Stand the Test of TimeAurora Consulting
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

1. Are you ready for more Website visitors? Best Practices to realistically load test your applications beyond the firewall Hari Ramachandran, Project Manager, Cognizant Colin Mason - Product Manager, Gome z
3. Need for Positive User Experience Internet users has increased from 360 Million in 2000 to 1.8 billion in 2009. Around Twenty Five per cent of the world’s population now use the Internet. North America (74%) has the highest penetration.
4. User Expectations Not Met at Peak Times Impact the Business 67% of online consumers expect consistently good experiences at peak times regardless of website traffic, but their expectations are not met Poor web experiences at peak times impacts revenue, brand & loyalty 78% of consumers have gone to a competitor site due to poor performance at peak times After a poor experience 42% have discussed it with family, friends, peers or online 47% left with a less positive perception of the company 88% of online consumers are less likely to return to a site Total Sample (N=1538)
5. Many of the industry’s largest merchants suffered site slowdowns or other problems in 2009 Non Functional Requirement’s are not properly defined and tested Web server/App Server/Middleware/Database server are not properly configured Database is not properly tuned Application is not designed to scale for huge volumes Infrastructure is not properly sized 3rd party components or services components didn’t scale under load
6. Make informed business decisions about capacity, third-party components & services, or future expansions plans Verify response-time and end-user experience under load Find problems and bottlenecks before real end-users are impacted Mitigate risk when launching promotions, rolling-out new applications or features, upgrading or virtualizing infrastructure, or anticipating seasonal spikes in web traffic Protect online revenue when it matters most, at peak times Ensure performance and availability of key transactions across geographies, for expected user load and beyond Why Performance Testing is Critical? Ensure success of critical Web-based business initiatives Validate speed, scalability and stability Deploy applications, new features & infrastructure with confidence
7.

9. When to Performance Test in Development Lifecycle Requirement Analysis Gather the Non Functional requirements – Involve all stakeholders Convert the business requirements into measurable performance Development Early Performance Testing/ Component Level Performance Testing Application Profiling Design Architectural Benchmarking Software benchmarking Hardware benchmarking Integration & Testing Pre Production Performance Testing – Load Testing, Stress Testing, Spike Testing, Endurance Testing, Volume Testing, Real End User Testing Implementation Application Performance Monitoring Performance Benchmarking
10. Recommendations For Successful Performance Testing Start early in the project lifecycle Gather Application Usage Statistics - Workload Analysis, Business critical transactions, User locations , Resource utilization Define Performance Testing objectives Identify the right tool for Performance testing Tool Inside the firewall – HP Loadrunner, Micro focus SilkPerformer, IBM Rational Performance Tester, Microsoft VSTS, Radview Webload, Neotys NeoLoad, OpenSTA, Jmeter Outside the firewall – Gomez Reality Load Have Production like environment Scripting – Parameterization, Correlation, Error validation, Smoke Tests Deploy Monitors to collect server side statistics Execute Baseline tests, Plan for iterative Performance testing
11. Performance Testing & Problem Diagnosis Design Phase : Architecture Performance Benchmarking Application prototype was becnhamarked on the planned production environment Early identification of design issues and uncovered major performance risk posed by the third-party products saving huge cost and effort Company: Real Estate and Relocation Services Building a new online real-estate transaction management system Perform End to End performance Testing Excessive Threads Spawned High Virtual Memory Usage After implementing Thread Pooling & Fix Patches From Third-Party Components
12. Performance Testing & Problem Diagnosis Development Phase: Early Performance Testing Early identification of critical code-level performance issues resulted in significant cost and effort saving for all stakeholders After fixing, the application code was stable and enabled increased scalability and better performance It is seen that the available memory goes down as the number of loaded assemblies increases Number of loaded assemblies keeps increasing throughout the test, although the same transactions are repeatedly executed Heap dump data showing many dynamically loaded assemblies in the heap Memory dumps show that there are many dynamically generated XMLSerializer assemblies present in memory Cache the XMLSeraliazer objects after creation, so they are not created every time. This avoids multiple creation of assemblies With the fix, the number of assemblies load stabilizes 5 minutes after the test, while without the fix, it grows continuously
13. Performance Testing & Problem Diagnosis Integration & Testing Phase: Pre-Production Performance Testing Application Server configurations where optimized for optimal settings after iterative test execution cycle. This eliminated high CPU utilization of the systems Reduced the CPU utilization of the application server from 95% to around 20% Availability of the system was improved from 87% to around 99% Sudden drop in throughput after 70 users indicating a bottleneck. CPU Utilization also peaks indicating the server side bottleneck

Editor's Notes
Key themes: load testing helps ensure success of critical web based initiatives by reducing risk when launching promotions, rolling out new apps, upgrading infrastructure and anticipating seasonal spikes in traffic Talk track How much risk can your organization accept when launching new web-based initiatives? Whether it’s rolling out a new website or application, launching a major marketing campaign, upgrading or virtualizing infrastructure, or preparing for seasonal spikes in traffic, load testing helps you reduce risk and ensure success. Load testing ensures that your key web pages and transactions perform under load across all the geographic locations you care about. Problems across the entire web application delivery chain can be found and fixed prior to launch – maximizing revenue and protecting your brand. With today’s on-demand “2.0” solutions, load testing is accessible to more organizations and departments than ever before
Last updated or created: Nov ‘09 Changed title Changed script Key themes: State main benefits we deliver to companies Gomez offers a SaaS-based, easy-to-access solution Gomez is a healthy, established, market leader. Talk track Here is a brief overview of Gomez. We help organizations deliver quality experiences to their Web and mobile users. What is a “quality experience?” Optimal performance and availability – You’ll use Gomez to make your web site fast and always available. For example, one customer reduced page load time from 11 seconds to 3 seconds with Gomez. Quality operation across all users, browsers, devices, and geographies -- You’ll use Gomez to ensure you web and mobile applications work for all of your users, across all the browsers and mobile devices, and across all your key geographies. For example, one customer saves 50% in staff fees We also help you resolve any issues that arise with: Rapid issue notification with actionable diagnostics – if something is wrong with your website, Gomez will alert you immediately, along with diagnostics to help you identify and resolve the root cause. Insight into how these issues affect your business (revenue, brand, cost) – a web site’s performance can be the difference between a sale or a lost customer. One Gomez customer has seen a 10% increase in conversions because of Gomez. Some information about the division: SaaS platform – Gomez is on-demand. No installation required. You get quick startup and rapid payback. And it operates on the world’s most comprehensive testing network – over 100K+ global locations and growing organically every day 2,500+ customers worldwide – Any company who relies on their web or mobile application can benefit from Gomez. We work with very large brands, such as Microsoft, MySpace, Google, and Apple – in fact, 12 of the top 20 visited US sites use Gomez. We also work with as many small companies, ones you’ve probably never heard of. We have experience and experience with all of their businesses, and we share them with you. When you become a Gomez customer, you gain the benefit of that insight. Solid business performance -- Gomez is health and established. When it was an independent company, it had five years of consecutive double digit revenue growth, including 44% in 2008. Offices around the globe. We’re recognized as the industry leader – Forrester calls us “THE leader in Web experience management,” and says we’re in the “on fire” category. Gartner calls us a “cool vendor” to watch. And EMA says Gomez is one of the “few companies who gets it.”
In the past, fewer machines served up the same information on one network that now is distributed The applications have gotten more complex and they’re very distributed The average web application now includes SIX separate web applications and they can have an impact on your brand. Third parties can be ads or videos, marketing tracking of visitors. Most of these applications can perform very differently under load., Sometimes the only place that all of these third parties come together is in a browser on the end user’s machine. CDNs can have wildly different performance in different geographies. The effectiveness of your CDN has a huge impact on your user experience and how your customers view the performance of your application.
Last updated or created: Nov ‘09 Moved firewall to the right; more detail in data center Key themes: Many things can and do go wrong in delivering Web/mobile applications Your customer expects you to control them all – not just what’s in your data center You can control these issues, but you must be aware of them first Talk track What kinds of things can go wrong in this Web application delivery chain ? Unfortunately, there are a long list of possible issues. This slide shows examples of the various issues that can occur at any point along the chain. It’s pretty ugly, because there’s a lot that can go wrong. Some of these can occur inside your firewall, but they won’t show up on system monitoring tools. Have you ever heard of or experienced any of these problems? Are you using any third party or cloud services? Are you using a CDN? Do you know if your application runs on every browser and O/S and mobile device? They happen every day. And the harsh reality is: they change everyday, too.
