As Walmart.com’s former head of Performance and Reliability, Cliff Crocker knows large scale web performance. Now SOASTA’s VP of products, Cliff is pouring his passion and expertise into cloud testing to solve the biggest challenges in mobile and web performance. The holiday rush of mobile and web traffic to your web site has the potential for unprecedented success or spectacular public failure. The world’s leading retailers have turned to the cloud to assure that no matter what load, mobile and web apps will delight customers and protect revenue. Join us as Cliff explores the key criteria for holiday web performance readiness: Closing the gap in front- and back-end web performance and reliability Collecting real user data to define the most realistic test scenarios Preparing properly for the virtual walls of traffic during peak events Leveraging CloudTest technology, as have 6 of 10 leading retailers

This document provides tips for successful project management when developing small Plone sites. It emphasizes the importance of thorough documentation, clear scoping, consistent processes, effective communication and follow up. Key aspects include writing functional specifications, tracking project status in a database, using checklists to track tasks, minimizing handoffs, reviewing projects frequently, soliciting client feedback, and identifying areas for process improvement.

This document discusses optimizing WordPress performance. It recommends minimizing frontend assets like CSS and images, using caching plugins to improve load times, optimizing themes and plugins, and choosing a fast web server like Nginx. Real-world tests show Nginx outperforming Apache. Specific tips include simplifying themes, deleting unused plugins, moving scripts to the bottom, and using a CDN with caching plugins to serve static assets quickly. The document emphasizes improving perceived performance through responsiveness, feedback and progressive loading.

Cliff from SOASTA and Steve from Staples discuss the three questions: How fast are you? How fast should you be? How do you get there? An overview of real world performance optimization and RUM.

This slide deck covers some of our Magento performances and optimisation best practices as we know them. We (NBS System) host 1800+ Magento shops since 2008, we hope this will help a lot of you to get good performances and enhance your conversion rate. It's not 100% complete coverage since it was a slide deck made for a 1H conference, but if you need more insights, contact us. Happy e-Commerce everyone!

This document discusses various methods for measuring front-end performance, including synthetic testing, active testing, real user measurement, and measuring the visual experience. Synthetic testing provides consistent results but may not reflect actual user performance, while real user measurement captures real user experiences but with limited detail. The document also covers specific tools like Navigation Timing, Resource Timing, User Timing, SpeedIndex, and services from companies like Soasta, New Relic, and WebPageTest that can help with performance measurement.

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.

The availability of on-demand, utility computing via the cloud introduces a new world of flexibility but also an entirely new charging model for applications. This new model has long promised to provide metered compute, charging you for exactly the amount of processing power you need, at the points that you need it. The cloud is a large paradigm change, not just for some of the technologies involved but also for the economics and the return on investment for deploying and running a given application. Whereas traditional on-premises applications require upfront capital expenditure on hardware, cloud deployments have an ongoing operational expense. Additionally, clouds typically charge by the amount of memory used, whereas applications are typically developed and tuned to run as fast as possible using all the available (already paid for) resources. Chris Bailey explains how this new economics of the cloud is driving changes in the way applications are architected, developed, and deployed. Presented at the O'Reilly Software Architecture Conference, London 2017

Responsive Web Design (RWD) is a giant leap in the right direction for web on mobile devices. However, RWD is just a small, part of the big picture. What we really want is for the whole value chain to be responsive, not only in the browser., There are a vast number of frameworks and tools on the webs for implementing RWD. Most of these provide a great starting point for mobile ventures. However, there are not so many tools out the to help you with the rest of the value chain. Especially tools that are easy to use and provide a relatively small footprint for front end developers., This talk will explore possibilities you get when you combine the best practices from the client side, with best practices from the server side. Sometimes this technique is called RESS, or Adaptive Design. The talk will contain coding, code samples and best practices based on popular frameworks and tools for Adaptive Design that combines client side and server side techniques. Results, effects and gains in terms of performance will also be documented and exemplified., The audience will gain insights into how their next project can perform even better in mobile devices and smart ways to reduce data traffic, increase speed and be more future friendly by utilizing the server for heavy-lifting.

You’ve been working with Microsoft SQL Server for a couple of years, and you know a little bit about TempDB. You’ve heard that temp tables and table variables have different performance characteristics than regular user database tables, and you’ve heard that you’re supposed to have multiple data files. You’re wondering what exactly goes on behind the scenes.

Progressive Web Apps are Web Apps which combines the best features of Web and Native Apps. It is progressive because it is constantly progressing.

Your website performance is crucial to its success. It is essential that you analyse your website’s speed and take critical steps to improve performance metrics.
