is “ab” or “httperf” better for checking performance of a website?

Question

so far i know of \"ab\" and \"httperf\", both can check the performance of a website. is one better than the other?

Answer 1

I found it was a bit of a mission to find useful documentation on httperf but there's a good (if you like screencasts) peepcode screencast that got me going with it.

I haven't used ab mind but I found that httperf seemed to work quite well once I figured out how to use it.
