In-depth technical analysis and benchmarks on web performance, load testing, and application optimization.
What effect does increased connection limits in the latest browsers (IE 8.0, FF 3.5) have on the performance of an Apache web server?
The latest crop of beta browsers, IE 8, Safari 4, and Google's Chrome are examined using the most popular websites to see if any of them are indeed faster than the competition.
Enabling dynamic compression in IIS 7.0 can reduce the bandwidth usage on a particular file by up to 70%, but also reduces the maximum load a server can handle and may actually reduce site performance if the site compresses large dynamic files. Read the full report for a complete analysis.
Enabling mod_deflate can reduce the bandwidth usage on a particular file by up to 70%, but also reduces the maximum load a server can handle and may actually reduce site performance if the site compresses large dynamic files. Read the full report for a complete analysis.
The latest installment in our PHP performance series takes a look at the open source APC module, which is described this way: "APC is a free, open, and robust framework for caching and optimizing PHP intermediate code."
The performance of our reference PHP application under load (a default SugarCRM installation) showed a 140% increase, measured by total system capacity, after installation of the Zend Platform.
The performance of our reference application under load (a default SugarCRM installation) showed a 14% decrease, measured by total system capacity, when running in a virtual machine.
This article measures the performance impact of the Zend Optimizer on a real-world processor-bound PHP application (SugarCRM) under load.
We evaluate Apple's performance claims for their Safari 3 Windows browser.
Virtualizing web and application servers makes them easier to manage, but how does it affect performance?
The results of an experiment that attempted to utilize AJAX techniques to reduce bandwidth consumption of a web application by at least 50%.
The performance of the Apache Tomcat server is compared on Windows vs. Linux when a memory limitation is present. This shows the marked difference in how the two platforms handle being resource limited.
The same tests as part one are re-run, this time with no memory limitation showing a marked increase in Tomcat performance on Linux over Windows.
The performance of a variety of servlet containers are compared, including: Tomcat 4.1.12, IronFlare Orion 1.5.2, Jetty 4.1.1, Caucho Resin 2.1.5, Sun ONE 7.0, and IBM WebSphere 4.0 (Advanced Single-Server).
