With 1812 checks you should really try having max_concurrent_checks at 0 
(unlimited) or at least roughly 300. Otherwise it won't have room for 
re-checks in case of failures, and you get latency. If 300 is too much 
for the hardware then adjust downwards.

Also, if you're using Nagios 1.x, the smart mode isn't really all that 
smart if you have different default_check_interval's, in which case it 
will do some seriously erratic math and come up with a check interval 
that is way too high for it to manage all of them.
