For comparison, my most heavily loaded data collector is a 2x Dual
Core AMD Opteron(tm) Processor 275 (2.1Ghz), 2GB RAM. It is running --
- Nagios 2.x polling 2225 services every 5 minutes (mostly ping, some
nrpe, some check_by_ssh, several other custom plugins); also
submitting results to 2 central nagios servers
- Cricket polling for 14,420 interfaces and updating corresponding
rrd files every 5 minutes

I also do not perform host checks but if you're on nagios-3, the
performance penalties of doing regular hosts checks are no longer an
issue as they are with 2.x.
