How to reduce a very high latency number

I have no hosts down 95% of the time, including now.  I could see how
that would be an issue, though.

I have turned off all logging, state retention, performance data
handling and backed off all timing parameters to their defaults (or
even less aggressive timings).  In a separate test, I changed only the
command_check_interval from -1 (check as often as possible) to 10
seconds.  Both have had seemingly no effect.  At this point, they 2
main servers I am looking at have been running for 30 minutes and
latencies are up to 540 seconds for the "bad" one and 48 sec for the
other one.


My next step will be to recompile with the latest nagios and try that.
 If that doesn't show an improvement, I'll try w/o perlcache.  Lastly,
I'll try without the embedded perl interpretter at all.
