Take a look at the min. spare servers, max spare servers, and num. servers to start. I keep these numbers low (10/10/10) to avoid old httpd processes. Theory is that a new connection gets a new, or not as old of an httpd server. My servers are not normal so YMMV. There is a lot of voodoo in deployments settings... I can second Chuck's experience with Apache 1.3. kib "The era of procrastination, of half-measures, of soothing and baffling expedients, of delays, is coming to its close.
