You absolutely 100% don't want to do this on a busy public web site,  
especially one behind a stateful firewall.  Many web clients open up  
multiple connections simultaneously and you then end up with a bunch  
of servers in keepalive state, where they could be helping others.

for a small load internal application, you won't notice the difference.

and if you have a stateful firewall, all those keepalive state  
servers will suck up all the states on your firewall in no time flat.

the redhat folks are not totally wrong in disabling it by default.
