i'd be deathly scared of running a loadbalancer that automagically handled slow/fast requests the way you expect. the configuration would be a nightmare, and it would be doing so much logging and profiling of request timings, it might negate the purpose of a load balancer to begin with.

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 :)
