No, you're still testing Rails' memory usage. If you want to test Mongrel's you need to write a non-rails Mongrel handler that does hello world. For example, here's the tests I run to make sure that I haven't destroyed Mongrel's memory usage: SERVER TEST VSZ RSS Mongrel Hello 20844 10564 Mongrel Rails 56092 39512 Webrick Hello 15180 4916 Webrick Rails 56548 39924 ruby IRB 4756 3252 ruby IRB_Thr 12952 3376 IRB_Thr is just irb run with a single thread in sleep. The two Hello apps are pretty close to the same, and the Rails apps are the exact same and show usage after the handling the same number of requests. What you can see is even though Webrick is smaller than Mongrel, it still ends up being the same size when it runs under Rails. That's why I say look at Rails if you want to save memory. Even if you stripped Mongrel down to the absolute essentials, the absolute impossible best is IRB_Thr. If you could get Mongrel down to Webrick's size, the test also shows it doesn't matter since the memory goes up to the same as when running mongrel anyway. No matter what, if you want to save memory you've gotta look at Rails and not Mongrel. -- Zed A.
