It depends on how you set things up. Whatever you use as a
"standard utility server" will likely do the job.
Here below is a snapshot of one of our servers.
We could probably reduce the CPU load and the disk requirement
for MRTG by using RRD mode instead of traditional rateup mode.

As you can see, that box has 45 instances of MRTG, covering
4845 targets. These include performance figures both from
network equipment (bit/sec, pkt/sec, etc) and from the local
server (CPU, disk, DNS query rate, NTP time sync, etc).
