London Web Performance Meetup: Performance for mortal companiesStrangeloop
You're probably familiar with the well-known performance success stories from companies like Amazon, Google, Microsoft and Shopzilla. But how relevant are these megasites to "mortal companies" that don't make billions of dollars per year or have teams of in-house performance engineers to do their bidding?
Strangeloop president Joshua Bixby walks through case studies of Strangeloop customers like AutoAnything.com and Artbeads.com to show how mortal companies have improved performance and achieved measurable success, including:
· Increased revenue by 13%
· Increased cart size by 6%
· Increased conversions by 9%
Joshua offers practical tips for successfully evangelizing performance within your organization. He also gives a snapshot of the current performance landscape in North America, as well as a sense of where the industry is headed.
Metrics, Metrics Everywhere (but where the heck do you start?)SOASTA
Not surprisingly, there’s no one-size-fits-all performance metric (though life would be simpler if there were). Different metrics will give you different critical insights into whether or not your pages are delivering the results you want — both from your end user’s perspective and ultimately from your organization’s perspective. Join Tammy Everts, and walk through various metrics that answer performance questions from multiple perspectives. You’ll walk away with a better understanding of your options, as well as a clear understanding of how to choose the right metric for the right audience.
Metrics, metrics everywhere (but where the heck do you start?)Tammy Everts
You want a single, unicorn metric that magically sums up the user experience, business value, and numbers that DevOps cares about, but so far, you're just not getting it. So where do you start? In this talk at the 2015 Velocity conference in Santa Clara, Cliff Crocker and I walked through various metrics that answer performance questions from multiple perspectives -- from designer and DevOps to CRO and CEO.

Magento Performance Improvements with Client Side OptimizationsPINT Inc
Discussion of various optimizations that can be applied to Magento community and enterprise installations for speed improvements. Techniques include common WPO techniques such as gzip, cache control, CSS spriting, domain sharding, byte code caches, reverse proxies and more. Various steps are applied to an Amazon AWS instance with the results from Webpagetest.org shown afterwards.
Walmart proves the obvious, devknob wonders why people don't understand why page speed matters. This has been true and known to be true since the beginning of the internet. Do you think people won't get distracted easily and bounce when they're surfing on 2g, 3g and even 4g connections? Page speed matters, devknob is probably the best page speed optimizer in the world so if you need conversion optimization, you may want to visit devknob online at devknob.com
An overview of web performance automation in the Production environment - "faster ways to make your website faster". Covers things like sample .htaccess files through to performance accelerators like mod_pagespeed and Aptimize through to DSA's like Cotendo.
This document discusses web performance optimization techniques. It is a summary of rules for web performance by Mark Tomlinson, who has 27 years of experience in performance. Some of the key techniques discussed include reducing HTTP requests, optimizing file compression, minimizing code, improving web font and image performance, prefetching resources, avoiding unnecessary redirects, and optimizing infrastructure and databases. The document emphasizes measuring performance through load testing and monitoring to identify bottlenecks.

In this talk, I talk about the different techniques coupled with few case studies on how to improve front-end performance.
The document discusses key reasons for poor web performance and how designers can improve it. It identifies that the front-end assets created by designers, such as HTML, CSS, JavaScript and images, account for 80-90% of page load time. Reducing the number of requests by combining files and reducing file sizes are the most impactful ways for designers to optimize performance. Large numbers of assets and large file sizes are the primary culprits of slow load times.
Delivering Optimal Images for Phones and Tablets on the Modern WebJoshua Marantz
Evolving mobile hardware and networks have made it challenging for web sites to deliver an optimal experience to each client. If you send the same image to both a WiFi Retina tablet and a 3G phone, you compromise speed and bandwidth cost against image quality. We'll look at using HTML and CSS image markup, CDNs, HTTP caching directives and how WPO can deliver a great UX with minimal effort.

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.

Jon Arne Sæterås - Give Responsive Design a mobile performance boost DevConFu
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.

Develop With Passion : It makes all the difference
This document summarizes information from the Nam Ngum River Basin Development Sector Project basin profile report. It describes the Nam Ngum river basin, including its area, average annual flow, population, and main economic activities. It notes that historically the basin had abundant water and fish, but economic development since the 1970s, including irrigation, hydropower, mining and other industries, has led to declines in fish catches and increased flooding risks. It outlines Laos' efforts to implement integrated water resources management in the basin through the creation of a River Basin Committee and secretariat to facilitate coordinated planning and management across sectors and provinces. The goal is to better recognize and address risks to balance development and environmental protection in the basin.

Metrics, metrics everywhere (but where the heck do you start?) SOASTA
This document discusses various metrics for measuring website performance and user experience. It outlines different types of metrics including:
- Network metrics like DNS resolution, TCP connection times, and time to first byte.
- Browser metrics like start render time, DOM loading/ready times, and page load times.
- Resource-level metrics obtained from the Resource Timing API like individual asset load times and response sizes.
- User-centric metrics like Speed Index, time to visible content, and metrics for single-page applications without traditional page loads.
It emphasizes the importance of measuring real user monitoring data alongside synthetic tests, and looking at higher percentiles rather than just averages due to variability in user environments and network conditions
Velocity NYC: Metrics, metrics everywhere (but where the heck do you start?)Cliff Crocker
This document discusses various metrics for measuring website performance. It begins by noting that there are many metrics to consider and no single metric tells the whole story. It then discusses several key metrics for measuring different aspects of performance, including:
- Front-end metrics like start render, DOM loading/ready, and page load that can isolate front-end from back-end performance.
- Network metrics like DNS and TCP timings that provide insight into connectivity issues.
- Resource timing metrics that measure individual assets to understand impacts of third parties and CDNs.
- User timing metrics like measuring above-the-fold content that capture user experience.
It emphasizes the importance of considering real user monitoring data alongside
Микола Ковш “Performance Testing Implementation From Scratch. Why? When and H...Dakiry
This document discusses the importance of performance testing and provides an introduction to the topic. It notes that performance testing determines how a system behaves under different loads and helps identify bottlenecks. The document outlines why performance testing is important from a user experience perspective, discussing metrics like page load times and the financial costs of poor performance. It then covers various performance testing approaches, targets, levels, and common metrics used to evaluate performance.
Performance is the most important attribute for success of any commercial and Enterprise Software. In a client server environment, developers focus a lot on optimizing the Data and Logical Tiers. Optimization of Presentation Tier which is responsible for more than 30 % of performance is usually ignored.
The document is developed with the intension to teach the technical staff on Optimizing the Presentation Tier which significantly improves the performance of the Client Server applications.
This session discusses how to maximize the performance of an application deployment with tools that are native to the server platform, as well as cross-platform Java analysis and monitoring tools include IBM Health Center and IBM Service Engage. The session begins with systematic steps organizations can take to locate a performance problem in a complex system and moves on to analysis they can do to understand the root cause of the problem. The picture is completed by consideration of the tools and techniques available to monitor application performance in normal operation so that organizations can catch performance issues before they build up into serious problems.
A Modern Approach to Performance Monitoring by Cliff Crocker, VP of Product Management, SOASTA
"How fast are you? How fast should you be? How do you get there? In this talk Cliff will discuss traditional approaches to performance measurement and introduce a ""RUM First"" methodology. This approach begins with capturing performance directly from the end user as the single source of truth for cross-functional organizations focused on performance.
Along the way, you will discover the relationship between RUM and synthetic monitoring, learn what to measure and how to capture it and finally how perceived performance impacts human behavior and your bottom line.

load speed problems of web resources on the client side classification and ...INFOGAIN PUBLICATION
This article is concerned about client side issues of web resources load process related to user agents (browsers) behavior. a lot of modern problems such as improving global availability and reducing bandwidth, the main problem they address is latency: the amount of time it takes for the host server to receive, process, and deliver on a request for a page resource (images, css files, etc.). latency depends largely on how far away the user is from the server, and it’s compounded by the number of resources a web page contains; current load algorithms are investigated and all known solutions with their area or efficiency are explained. We have described four main optimization methods.
The document discusses client side performance testing. It defines client side performance as how fast a page loads for a single user on a browser or mobile device. Good client side performance is important for user experience and business metrics like sales. It recommends rules for faster loading websites, and introduces the WebPageTest tool for measuring client side performance metrics from multiple locations. WebPageTest provides waterfall views, filmstrip views, packet captures and reports to analyze page load times and identify optimization opportunities.
Measure and Increase Developer Productivity with Help of Serverless at Server...Vadym Kazulkin
The goal of Serverless is to focus on writing the code that delivers business value and offload everything else to your trusted partners (like Cloud providers or SaaS vendors). You want to iterate quickly and today’s code quickly becomes tomorrow’s technical debt. In this talk we will show why Serverless adoption increases the developer productivity and how to measure it. We will also go through AWS Serverless architectures where you only glue together different Serverless managed services relying solely on configuration, minimizing the amount of the code written.
Optimizing WordPress PHP performance with TidewaysSeravo
Otto Kekäläinen, the code-loving CEO of Seravo, and Benjamin Eberlei, the founder of Tideways, held a webinar on June 4, 2020, where they discussed PHP performance optimization and how to get rid of performance bottlenecks in a WordPress environment.
Magento sites need optimization to load fast and provide a good user experience. Speeding up a site increases sales and improves SEO. Factors that impact load time include network transfers and the resource-intensive nature of Magento. Benchmarking tools like APDEX, Funkload, Yslow and Pagespeed help measure performance and set goals, such as loading the homepage in under 1.5 seconds. Architectures must be sized properly and include techniques like splitting front and back ends, enabling caching, and using a CDN. The Nitrogento extension automates optimizations like blocking caching, sprite generation, and asset minification to significantly improve performance.
1) Traditional load testing is limited in its ability to accurately measure end-user experience and identify issues with third-party components.
2) Load testing 2.0 uses real user testing from geographically distributed locations to more realistically drive large volumes of load and uncover regional response time discrepancies and external errors.
3) An online retailer used load testing 2.0 to identify that a third-party component was insufficient under load, affecting the performance of their overall application.

Build it Right, Deploy it right:
Follow best practices. Everyone must be aware: Do share perf tips
learned here with your team!
Eliminate 404 and un-necessary redirects
Reduce # of images, Optimize images, Compress, Minimize payload,
bundle
Cache it right, Use CDN, Avoid too many hosts but not too less too.
Interpret Page test results correctly and take action
Write Quality code – High Performance code
Put Special Focus on Front-End, a typical problem area
Identify critical screens, too much focus on home page can backfire
ACTION STEPS
23. 2014 TBC-World 23
Benchmark/Optimize/Automate:
Conduct User Experience Studies. Conduct Perf. tests
on load and otherwise
Benchmark/Optimize: Make Page speed test (Use Yslow
or Google speed test) part of regular sprint test. If
possible, automate it right into continuous integration
scripts , where possible.
Consider Deployment of Dynamic Site Acceleration
Solutions like Akamai/YOTTA when demands are for sub
3 sec page load, across geographies
