Performance... somewhere Zed has an article on how to benchmark things..
something along the lines of benchmark a blank static html page. That's
as fast as your server will go. Then create a simple action that renders
"Hello" as text say, with one mongrel. Benchmark that. Keep increasing
the number of mongrels until you don't get any more performance
For us, it was 4.
