Performance Tuning PHP

Since the webserver plays an important part in the request serving process, it is important to tune it. A big part of this is the Apache child creation process.

• StartServers set to avg. # of requests you'd expect.

• MaxSpareServers keep this number high, to allow Apache to gracefully handle traffic spikes.

• MaxClients keep this number at about 2/5 of the maximum processes your server can handle.

• MaxRequestsPerChild ideally unlimited (0), but practically should be limited to a large number.
