Topic: How to test Performance of every web server running my raisl app?

I used to test  run(test) my rails application with webrick during development,and last week I installed mongrel.I just felt mongrel is a little faster than webrick.

But I want to know how to use tool (and what tool)to test Performance in production between webrick and mongrel or some other web server(apache, lighttpd, thin etc.)

Who can give me some advice about Performance test in a real time(imagin 1000 people online)?

Thanks.

I am on rails.
