About the HTTP Archive Successful societies and institutions recognize the need to record their history - this provides a way to review the past, find explanations for current behavior, and spot emerging trends. In 1996 Brewster Kahle realized the cultural significance of the Internet and the need to record its history. As a result he founded the Internet Archive which collects and permanently stores the Web's digitized content. In addition to the content of web pages, it's important to record how this digitized content is constructed and served. The HTTP Archive provides this record.
http_load http_load - multiprocessing http test client Fetch the software. http_load runs multiple http fetches in parallel, to test the throughput of a web server. However unlike most such test clients, it runs in a single process, so it doesn't bog down the client machine. It can be configured to do https fetches as well. You give it a file containing a list of URLs that may be fetched, a flag specifying how to start connections (either by rate or by number of simulated users), and a flag specifying when to quit (either after a given number of fetches or a given elapsed time). Joe Dog Software - Siege Manual Introduction Siege is an http/https regression testing and benchmarking utility. It was designed to let web developers measure the performance of their code under duress, to see how it will stand up to load on the internet. It lets the user hit a web server with a configurable number of concurrent simulated users. Those users place the webserver “under siege.”
Optimizing PostgreSQL/Tomcat for Write-Heavy Workloads Recently I've been working on tuning the performance of a Tomcat web front-end and PostgreSQL back-end. In particular I wanted to stress some write-heavy scenarios, so I designed a JMeter test plan and ran it using Maven Chronos (as described in this post). Also I have collectd running on the machines and reporting various system metrics to a central server for graphing. This is essential to help identify which system resources are contributing to a performance bottleneck. In this post I don't want to get too hung up on the exact nature of the queries or the hardware configurations.
AM Stereo » Blog Archive » Using Tsung for Load Testing Rails or Web Apps September 12, 2008 by Austin Mills After trying some other load-testing tools, I found Tsung, a load-testing application written in Erlang to take advantage of that language’s concurrency support. It scales well (it’s been used to simulate tens of thousands of users), it supports forms and HTTP sessions, and includes some niceties like proxy recording, ‘thinktime’ support, and a choice of random or ordered traffic. Not having a physical server handy to run Tsung isn’t a big obstacle; I just used an Amazon EC2 instance (an xlarge turned out to be more than enough, you could probably get 100s of users on a medium), which due to being rentable by the hour is great for a short-term need like occasional load-testing. I put one of Alestic’s Ubuntu images on the EC2 instance, and then it’s just a few short steps to install Tsung on the machine (we’ll call it ‘tsunghost’):
Dynatrace AJAX edition Dynatrace AJAX edition has been a great product and helped many people around the world to analyze web performance problems in Internet Explorer and Firefox. Endorsed by industry experts such as John Resig (creator of jQuery) or Steve Souders (creator of YSlow) AJAX edition became the de-facto standard for browser diagnostics on Internet Explorer and Firefox on Windows. With the extension of Web Performance into Mobile Devices, Cloud as well as different server-side technologies (Java, .NET, PHP, Nginx, Node.js, …) Dynatrace decided in December 2014 to focus the efforts and continue innovation of Browser Diagnostics, User Experience and Application Monitoring into Dynatrace. To get your own personal license of Dynatrace Application Monitoring and Dynatrace User Experience Management simply sign up on this page or use the on We still provide the old Dynatrace AJAX edition download in case you want to hold on to its legacy.

Web E<sup>x</sup>ponents - The official Google Code blog Over the last few months, I've started inviting web gurus I know to give tech talks at Google. It's been great to kick off this speaker series with such luminaries as John Resig, Doug Crockford, and PPK. (I snuck in there, too.) The biggest benefit from these talks is the release of the videos and slides. The videos are popular, with thousands of viewers.
