Nagios performance is very much specific to your environment. Nagios 3.x is also MUCH faster than Nagios 2.x because of parallel host checks (and other features.) Our performance is summed up below but your millage my vary:
Primary server: Nagios 3.0.3 Dual, quad-core processors @ 2.4 GHz and 4GB of RAM ~650 hosts, 1550 services System load averages 0.8, 0.6, 0.5 (CPUs are mostly idle with spikes when hundreds of checks get kicked off at once) Average service check latency 0.3 seconds Average host check latency 2.5 seconds All of our service checks are active, mostly snmpget and snmpbulkget and lots of pings - largely checking every 2-5 minutes. Most of our service checks are bash and perl scripts (we don't use the embedded Perl interpreter.) We also collect and parse perfdata for graphing and run Cacti and other very small MySQL-driven webapps on this same server. The server is definitely a little over-kill but the price was right and it was purchased with Nagios 2.x in mind - once again, Nagios 3.x is much faster. Our environment is also not "tuned" for performance other than to put in sane timeouts for service checks so they don't sit around waiting too long.

LS, I've searched the internet (maybe I look in the wrong places) but I can't find any numbers on sizing a nagios server. Are there any numbers out there amongst you and are you willing to share?
