> Hello everybody, 
> I'm running mrtg 2.8.8. on a RedHat Linux 6.0, on a 200 Mhz Pentium, 96 MB
> memory. I have about 56 configuration files, with about 500 targets. Most
> targets are on our LAN, I'm monitoring the traffic and error rates of our
> switches. However, the machine cannot keep up with 5 minutes period and I
> need to add several more targets into my base. So, this makes me quite
> worrying. 
> I did a search in a mailing lists archive and found some recommendations
> for tweaking hard disk performance and switching over to another tool.
> Regarding the hard disk, I ran hdparm and gained about one third of
> throughput, but it didn't helped too much. When it comes to switching the
> statistics tool, I'm not too keen on it. 
> So, have anybody ran into similar problems and maybe have some
> recommendations, what should I do. Put a brand new 500 Mhz machine into
> place ? Melt configuration files into one single piece ? Run mrtg in mode,
> in which the gif files aren't generated every time ?
