I am one of the server administrators of a busy news site and I've been trying to find a definitive answer/guide for choosing MaxClients. We run a farm of six Linux webservers each with 8GB of RAM and several distinct Apache instances on every server. The main instance, which gets most of the traffic, has a MaxClients setting of 768, and is using the worker MPM. Considering that $ ps -fwwylC httpd.worker --sort:rss on each shows the average memory consumed by each process to be ~30MB, is our MaxClients setting too low? Far too low? We do occasionally run into situations during peak times when MaxClients is hit, but I'm reluctant to increase it for fear the webservers will start swapping. - Julian -- -- Julian C.
