Benchmarking Rails for Applications / Web Servers

Question

Does anyone know the best lightweight Rails benchmarking tool?

I need to get web server performance statistics and simulate authentication + page navigation per session. I tried to use httperf, but met a TamperingWithCookie exception in the application.

Ideally, I would like to separate the application and the database from the benchmarking of the web server, but it is interesting to see the results of their combination.

Answer 1

You can try Tsung , a distributed load testing tool written in Erlang. This is a common tool, but it can be easily used with Rails applications. If you need to model different user behavior scenarios as a kind of integration tests, you can also try Webrat .

Answer 2

ruby-prof works well if you manually hit your application using a browser or you can compare tests.
