Velocity NY 2013 - From Slow to Fast: Improving Performance on Intuit Website...Jay Hung
Convincing an organization that performance matters and is worth investing in is often a tough thing to sell. This was no different at Intuit, who operated many sites built in the pre “web standards” era. Then, one day, one test changed everything – an A/B comparison successfully demonstrated that faster page loads increased conversion and SEO. And the conversation quickly changed from “Not interested” to “How quickly can you make the rest of our pages faster?”
A performance team was formed, and optimization began across multiple properties in a phased approach with each release delivering incremental performance gains. As we iterated through the core performance principles, the team introduced additional techniques that led us to exceed our original performance goals. Techniques such as lazyloading, prefetching, smarter image optimization/spriting, and module rewrites enabled us to successfully shave off additional time.
This session will cover the steps that we took, lessons learned including what worked well or didn’t work well, as well as the performance improvements that were realized, and their impact on business metrics. Some of the topics include:
* How we went from 15s web pages to 2s web pages
* How combining CSS/JS files and image sprites had both positive as well as negative impact
* How lazy loading of resources and JavaScript rewrites improved our page render times (including our experiments with Control.js)
* How we addressed blocking as well as high-latency third-party components
* How we solved for issues/constraints arising from shared code across multiple sites
* How we optimized for user flows spanning multiple pages with positive results
* How automated benchmarking enabled us to continuously monitor our performance health
* How we succeeded in making “performance” a common theme among developers, marketers, and stakeholders

The document discusses osteoarthritis (OA) and potential new treatment options. It summarizes several studies on treatments such as glucosamine, chondroitin, anti-nerve growth factor (NGF) drugs, and anti-osteoporosis drugs. One study found strontium ranelate reduced joint space narrowing in OA patients compared to placebo. Another international study on strontium ranelate for treating knee OA is described, which found both lower doses of strontium ranelate significantly reduced joint space narrowing progression over 3 years compared to placebo.
Use Gzip compression to reduce the file size of CSS, HTML, and JavaScript files over 150 bytes. Do not use gzip on images; instead compress images in Photoshop. Minify CSS, JavaScript, and HTML code to remove unnecessary characters and increase page speed. Reduce the number of redirects between pages to decrease loading time. Leverage browser caching by setting expiration headers to cache site assets for up to a year unless the site design frequently changes. Improve server response time by fixing performance bottlenecks. Use a content distribution network to distribute site content across multiple servers for faster loading. Optimize images by reducing file sizes and using CSS sprites to load images in one request.
Front end optimization is important because 80% of end-user response time is spent on the front-end and front-end optimization can cut page load times by 25-50%. Page load times significantly impact user experience and business metrics. Tools like Yslow and Google PageSpeed can help identify optimization opportunities. Image optimization, minimizing HTTP requests by combining files, and reducing payload sizes are some techniques that should be applied from the start of a project. Progressive page loading, splitting components across domains, browser caching, and preloading components can further improve performance.
Improving web site performance and scalability while savingmdc11
This document discusses various techniques for improving web site performance and scalability while reducing costs, including:
1. Optimizing code to reduce HTTP requests and payload size.
2. Leveraging browser caching through content expiration, HTTP compression, and cache validation.
3. Minifying and consolidating CSS and JavaScript files.
4. Using a content delivery network (CDN) to distribute static assets globally.
5. Caching data and view state to reduce database queries and payload size.
This document provides instructions on how to build a content delivery network (CDN) to improve website performance. It discusses how page sizes and mobile traffic are increasing, causing slower load times. A typical website loads resources from a single web server, taking 10 seconds. Using a CDN can get content closer to users, load resources in parallel, and improve speeds. The document reviews existing CDNs and how to set up an on-premise or cloud CDN using technologies like Azure CDN, which can deliver content to users worldwide from multiple edge servers for faster load times.

The document discusses website performance and optimization. It notes that nearly half of users expect a site to load within 2 seconds and will abandon a site taking longer than 3 seconds. Common issues causing poor performance are bloated templates, unnecessary code, and too many HTTP requests. Suggested optimizations include minimizing assets, prioritizing visible content, image optimization, caching, compression, and lazy loading. Case studies show significant speed improvements after implementing optimizations. Metrics like Speed Index measure how quickly visible content displays to influence perceived performance.
The document provides best practices for optimizing frontend performance by reducing page load time. It discusses ways to reduce the number of HTTP requests, DNS lookups, redirects and duplicate scripts. It also recommends techniques like minifying assets, leveraging caching, prioritizing critical components, optimizing images and using content delivery networks.
The document discusses various techniques for optimizing UI performance, including optimizing caching, minimizing round-trip times, minimizing request size, minimizing payload size, and optimizing browser rendering. Specific techniques mentioned include leveraging browser and proxy caching, minimizing DNS lookups and redirects, combining external JavaScript, minimizing cookie and request size, enabling gzip compression, and optimizing images. Profiling and heap analysis tools are also discussed for diagnosing backend performance issues.
This document discusses optimizing the client-side performance of websites. It describes how reducing HTTP requests through techniques like image maps, CSS sprites, and combining scripts and stylesheets can improve response times. It also recommends strategies like using a content delivery network, adding expiration headers, compressing components, correctly structuring CSS and scripts, and optimizing JavaScript code and Ajax implementations. The benefits of a performant front-end are emphasized, as client-side optimizations often require less time and resources than back-end changes.
This document discusses various techniques for improving the frontend performance of Drupal websites. It begins by introducing the speaker and describing the goals of the presentation. The bulk of the document then provides recommendations in three areas: backend server optimizations like caching, parallel downloads and gzip compression; tools for measuring performance; and frontend optimizations like minimizing requests, lazy loading images, and improving CSS and JavaScript. The document encourages proper performance diagnosis and defines goals before implementing solutions.
AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes, allowing parts of a page to change without reloading the entire page. Tuenti uses AJAX extensively to update parts of their single-page application, caching content on both client and server sides for scalability. They route requests to different server farms based on client location and cache content to improve performance. Tuenti serves billions of images per day using multiple CDNs and pre-fetches content to minimize load times.
As we all know that speed is one of the most important issues for the success of a website. No one wants to wait for a site to load and that’s why we need to minimize the loading period when building a Joomla website.
Web performance optimization can be done at three levels - general, server-side, and technology. At the general level, techniques include minimizing HTTP requests, optimizing images, minifying files, avoiding redirects and empty sources. Server-side optimizations involve techniques like content delivery networks, cookie-free domains, caching, and gzip compression. At the technology level for dynamic sites like Joomla, optimizations include flushing buffers early and optimizing database queries. Performance can be measured using various online tools.
This document discusses optimizing Joomla templates for high performance. It recommends tools like Firebug and YSlow to measure performance, and optimizing assets like JavaScript, CSS, and images. JavaScript should be moved to the end of the page, unused code removed, and files minified and compressed. CSS should be moved to the head and stripped of unused rules. Images can be optimized by using sprites, compression, and delivery via a CDN. The optimization process involves these techniques applied at each stage of development.
Did you know that 80% to 90% of the user's page-load time comes from components outside the firewall? Optimizing performance on the front end (e.g. from the client side) can enhance the user experience by reducing the response times of your web pages and making them load and render much faster.
Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data.
The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs.
Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution!
Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.

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

2. In the blink of an eye…
You only have one chance to make a first impression.
"In the blink of an eye" your site (blog or website) is judged.
With so many sites and blogs to choose from, a site that loads
at a snail's pace or is hard to navigate will send frustrated
potential visitors on to their next destination.
Good design, effective usability and speedy site performance
are three very important considerations for building and
keeping an audience. They add to your credibility and help
build your audience’s trust, which is the only way to achieve
user loyalty.

7. Broadband Statistics
In high traffic site, if pages are optimized for
lower weight, the company can save a lot of
money on bandwidth charges. And why
should
For example, 100,000 pages of 150Kb weight will I care?
need twice the bandwidth as the same number of
pages at 75Kb.
So, if the ISP, charges by the amount of bandwidth we use, that’s how
reducing page weight can save the company big time on monthly
bandwidth charges.
8. Impatience Index
There are still a large number of outdated computers and slower speed
