I ran into something like this, not that long ago.  Host and service 
check latencies being very high, like almost 15-20 minutes.  After some 
research, the suggested fix was to modify the check_host_alive and 
related commands.

Change them so they only use a single packet to check.  Add "-p 1" as a 
flag to your ping-type check commands.

Once I followed this advice, my average latency went from 900 seconds or 
so, to usually less than a second.

We monitor about 250-300 devices, 95% of them only have a single service 
check.  (Usually SNMP)
