[mrtg] New Mrtg Server very high CPU usage.

[Mersberger, Robert]

I have just completed the install of my new Mrtg server on which I am
running the following 
Server IP is 172.31.16.237  : Note This is a VMware Server  with two
CPU's
Linux mrtg2.beverlycorp.com 2.6.25-14.fc9.x86_64 #1 SMP Thu May 1
06:06:21 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
MRTG.x86_64 Version 2.16.1	
RRDTOOL.x86_64 1.3.0
RRDTOOL-PERL.x86_64 1.3.0
Routers2.cgi Version 2.18beta5 

I am monitoring about 560 sites and have notices that the CPU spikes to
99% every 5 minutes  and know that this is when my script is running. 

What I would like to know is if there was someway to throttle these
processes to lower the cpu usage.  Here is a copy of the script that
runs via a cron job every 5 minutes
#############
mrtg_run
############
#! /bin/bash

for fn in /etc/mrtg/*.cfg; do
        env LANG=C /usr/bin/mrtg "$fn" &
done
####################################

I am looking for ways to improve performance  have some cpu left over
for other task.

Precisely the same as .cfg files.  In fact, you could call them .foo, or
.mrtg, or .LifeIsGrandInGrandSaline, or not even have an extension.
Perl doesn't care - it's just text.
