OK, you have a performance issue.  As Lars said, you have to look at a lot
of factors to figure this one out.  For starters:  what kind of box is
this, how much memory?

How many Apache processes are allowed (httpd.conf MaxSpareServers,
StartServers, MaxClients) and how many are actually running (ps ... | grep
httpd)?  Try turning down the maximum number of clients and see if
performance improves.

A big one:  Is the box swapping?  Run "vmstat 5" and watch it for several
lines.  Swapping can cause high load in a hurry.  Reducing the number of
Apaches will help that too.

Subject: How do I upgrade (use the patch files)

Forgive me... I'm sure the answer is simple, but how do I use the "patch"=

program to upgrade to the latest version using the patches?

I'm running RedHat Linux 7.0 ...

Thank you for the help and the great work,
