Siege for Apache

Siege is stress test and benchmark utility. It can stress a single URL with a user defined number of simulated users or it can read many URLs into memory and stress them simultaneously. The script is still very actively developed.

It looks like apachebench over-reports responsiveness when serving static HTML or minimal PHP scripts. The Siege is more accurate in reporting static HTML and PHP responsiveness. In all technicality they are the same, Siege just doesn’t require apache-tools.
