Had to reply to this one since I actually studied Max's blog articles 
for ideas when I was researching performance tuning.  Thanks Max for not 
only pioneering some of these ideas, but actually documenting what you 
did.  ; )

  Nagios XI Benchmarking Test Box
- Running on one of our old Desktops:  1 Dual Core CPU, 4GB of RAM, 
CentOS 5.7
- Ndoutils/MySQL offloaded to a second server
- 1800 Hosts, 8200 services, 10k checks running every 5mn
- Processing perfdata for all checks
- rrdcached in use with PNP
- RAM Disk being used for status.dat, objects.cache, host-perfdata, 
service-perfdata, all spool and tmp directories
