Howto: Performance Benchmarks a Webserver

Apache Benchmark Procedures

• You need to use same hardware configuration and kernel (OS) for all tests
• You need to use same network configuration. For example, use 100Mbps port for all tests
• First record server load using top or uptime command
• Take at least 3-5 readings and use the best result
• After each test reboot the server and carry out test on next configuration (web server)
• Again record server load using top or uptime command
• Carry on test using static html/php files and dynamic pages
• It also important to carry out test using the Non-KeepAlive and KeepAlive (the Keep-Alive extension to provide long-lived HTTP sessions, which allow multiple requests to be sent over the same TCP connection) features
• Also don't forget to carry out test using fast-cgi and/or perl tests
