Stop thinking small. When you have many thousands of checks
to run, tiny delays persist and add up. A second here, a
second there, and pretty soon you're talking real time.

The design issue is that delays build up and become very
observable.


I've removed the sleep in my version of nagios and throughput difference is=
DRAMATIC.
That said other things are having a hard time running on the same machine.
I'm going to sprinkle some yields where the sleeps are at and see if that h=
elps, I'll keep you apprised.

Sincerely,
Steve
