well, I dont't want to configure explicitly where requests go.

There are hardware balancers which do that (which cost a fortune) and
the upcoming lighttpd release seems to support something like that
(Shortest Queue First):

I'm not really sure if that's the solution for my problem and I realize
that advanced logging and profiling is not cheap. It just seems to me
that it's a common problem with rails (fast requests coming from
fragment caching etc, slow requests from complex pages with lots of db
queries) and was hoping others found a solution for it :)
