Also, Ryan, just to make absolutely sure we're talking about the same
thing: what exactly do you mean by "even load balancing"? Also what do
you mean by "n mongrel instances on the front-ends sitting behind
perlbal", do you mean you have additional proxy load balancers behind
perlbal, and the mongrels were behind that second layer of load
As an aside, did you write your own munin plugin to look at how evenly
balanced your mongrel pool was?
