What is the ratio between them? I've runned across this issue, and had to tweak with main config values to solve the problem.
To me, when i've came to this problem, the number of passive checks were way beyond the number of active checks, and seemed that when a lot of passive checks were being processed, the active checks begins to delay execution, the latency begins to raise, and only restarting nagios to get some performance again, until the burst of passive results coming and Nagios being way too busy for executing active checks. The number of nsca instances was very high and when i've changed the value at command_check_interval from -1 to 2, the latency lowered. So, IMHO, i think it's a question of configurations tests to get performance tunned.
