i forgot the one, which had the greatest impact
enable_environment_macros=0
When we disabled the macros, the load dropped from 40 to 10. If you don't
have self-written check/notification scripts which use the environment
variables NAGIOS_*, then it is not worth to waste cpu cycles translating
macros into environment variables.
My impression is, when you reach > 7000 services, Nagios spends too much
time with internal calculations. That's why we turned off these "smart"
settings.
