high latency

[Daniel Wittenberg]

Yeah, been running that since day one, since when rollout is done we'll
probably have about 18k servers and around 3 million service checks...

I can probably post my relevant config options if someone wants to peak.

Hey Dan,

   I too have been wrestling alligators with service and host
check latencies averaging around 60s, and increasing to 100+
(sometimes to 300) after a few reloads during the day.

   This morning, I enabled the use_large_installation_tweaks
option.  As of a minute ago, my host check latency is now
averaging 2.116s, and service check latency is averaging 0.748s.

   I didn't see if you had tried this yet, it might be something
to consider.

Benny
