  I am not clear here.  Since our load-test kept
sending the requests continually, the children with
keep-alive connections should not be stuck in waiting
for requests. Am I right?  still not clear why
keep-alive slows down the performance?

  I also think, if the number of free/available
children is big engough, a portion of children being
stuck waiting for requests on keep-alive connections
should not slow down the performance, right?

Event mpm is really the one we are looking for. 
However, it seems still a experimental MPM.  Could you
tell me how stable event mpm in 2.2/2.3?

Many Thanks,
