I had this problem and Jason describes one work-around to it (making host checks complete as fast as possible). My solution was to disable all host checks (my latency was still too high even with fast host checks).
My understanding is that Nagios must complete the host checks of a down host before ANY service checks on any host are performed. If a host is down and your checks are configured to run over X number of minutes Y times then you are stalled for that long. If you have multiple hosts down then you can just multiply your latency. Prove this to yourself by going in to each configured host that you have that is down and disabling the host checks. Your service checks should come right up to time.

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.
