I am hoping you might gracefully suggest what we might be able to do
to improve our problem of memory usage being consumed by apache.
We have a turbo gears type web server with 2GB ram which is running a
point of sale system for about 15 or 18 stores.
We are running mod_wsgi 2.5, but about to upgrade to 3.3.
Is it typical for one process (wsgi:rarch) to consume virtually all
the CPU and memory consumption while the remaining apache children
seem to not be doing much?
Is it typical for memory consumption to increase throughout a day?
I've been reading the release notes, was lazy initialisation of Python
interpreter already existent with version 2.5?

Thank you so very much for any time you spare to point me in the right
direction, documentation regarding memory management with mod_wsgi,
etc.
