I don't know enough about RHEL (and it's clones) to know why this might
be a good idea. Could you tell me a little more please?

I see.

MSMRTG says that the server has an average of 7% CPU Utilization (for
the past year with very consistent usage throughout) and load average is
only an average of 0.1 (for the year as well).

Here's the output from free:

             total    used    free  shared  buffers  cached
Mem:        255384  220580   34804       0    58668   75688
-/+ buffers/cache:   86224  169160
Swap:       264560   15968  248592

Does this info help indicate at all what I might be able to handle in
the future?

Would you mind explaining a little about what those differences are?

I'll see what I can do. I might have some laying around.

Same with me.
