Hi Jochem, Apache comes with an nice ab tool which stands for apache benchmarking. You can use this to benchmark stuff like concurrent requests.

indeed, I know ab, but it doesn't allow for a very realistic request 'spread' - at least as far as I know. Indeed it doesn't, but you appear to want to figure out what optimization works best. You don't need realistic spread for that, even more I think you shouldn't want realistic spread for that but something comparable instead. If anything, the result of ab are very useful for comparing results.

I was hoping for a bit more detailed info on mimicking real-world site usage, e.g. maybe using access logs as a source of url data?

hi guys, I need to do some performance testing for a site of mine. I want to compare performance of various combinations of using APC, Squid, Apache/LightHTTPD mod_php/fastcgi. all very well I can build the various setups but I'm stuck as to how to go about recreating realistic load on the machine in question. I don't want to have to go out and buy some commercial software. STFW is making my head spin. Does anyone have any tips, urls, advice as to how to start going about creating something like a 'test suite' for testing high load performance of a website? TIA
