I have no idea what you did to Nagios to make it run only 60 checks per
minute. With a distributed setup, using 5 virtual machines and Merlin to
connect them, I've managed to schedule, run and reap roughly 750k checks
per 5 minutes. Clearly, you're doing something amazingly weird in your
configuration. Have you set parallelize_check to 0 in some template
somewhere, or turned it off globally in nagios.cfg? Are you using an
OCS[PH] command that takes forever to run, or is your perfdata handling
completely bonkers? 60 checks per minute is nothing, and if that was the
limit of what Nagios can manage to execute, nobody would use it.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
