like Bill, I'm curious to know any details.  I'm guessing:
* this is more of a 1.3 issue,
* the servers are constrained by memory, processes, or threads, and
* "KeepAlive off" makes it hurt less.

yep.  At the moment I think work needs to be done to reduce the overhead in 
passing a socket to the event thread before getting really serious about 
benchmarking.  But yes it should be benchmarked before too long.  Something like 
Kegel's web site suggests (4K download every second per simulated user) would be 
interesting.
