Latency in service checks

Hi, I have been facing some really heavy latency issues as well last time. I 
guess it depends a lot on the problems of the services that you are 
monitoring. Having too many critical services will lead to high latency. Are 
you having lots of critical issues? How are you moniotirng these services? 
Are they active or passive? You can try tweaking max_concurrent_checks and 
best is set service_reaper_frequency below 5 secs. Inter_check_delay and 
Service_interleave_factor is advisable to be set to SMART. 

You may want to look at these :
