Subject Re: [users@httpd] Apache 2.2.15 memory usage
Date Fri, 20 Aug 2010 10:22:59 GMT

Read this document:

My guess is that child processes consume extra memory, as the server
creates them when there are many clients connected simultenously. Note
that it's a perfomance optimization: child processes will be there
ready to handle clients when they arrive as soon as possible. Though
you could control how many child processes may hang around idle with
the MaxSpareServers directive:

Note that if you really restrict that, the server may lose performance
(ie. get slower), because then it needs to create the necessary child
processes when clients connect.

It's also possible that Apache caches some files those requested
pretty often, but AFAIK this feature is not on by default so you must
have manually configured it, so most likely you would know about it
