            | ? How to use a web server as a load generator? Long time ago we added benchmarking feature to this web server so it became also a performant client. It was done in order to be able to test high capacity phantom-based services. No other tool of that time was capable of generating such amount of load using only one machine. Phantom could.

There are response time quantiles for each second on it, so that you can examine that, for example, at 16:16:54 75% of responses were faster then 45 milliseconds. Give it a try!
