Apache KeepAlive

[Monie]

I've seen a lot of debate on sites, some saying do not use as it's a resource hog and others saying use it. What are your thoughts on it?

I currently have it off but when I had it on I used these settings..

KeepAlive Off
MaxKeepAliveRequests 5
KeepAliveTimeout 3

Do you think I'd be better off using KeepAlive?

KeepAliveTimeout means the time before the process ends, On my configuration I made it off because of too many processes.
