After reading all the political *and* technical responses to this
question, I'm really wondering now -- just what *is* the bottleneck in a
Rails server? Politics aside, Zed and some others went through some
amazing contortions, tweaks and hacks to get Mongrel robust and fast.

Overall web application server performance obviously depends on the
application -- how big the model is, how many different URLs, how chatty
the application is over the network, database design, etc. But I just
can't imagine the core web server part of it being a major bottleneck.
