High latencies problem.

   After setting the following parameters, latency dropped to 20s in my nagios sytem:

   status_update_interval=60
   auto_reschedule_checks=1
   check_result_reaper_frequency=60
   max_concurrent_checks=0
  
   The other parameters that you've sent me are also set, sleep_time, service_interleave_factor and service_inter_check_delay_method.
   Thanks a lot Daniel, Gerhard, Hendrik and Markus for the help and tips.

   []s.

use_large_installation_tweaks already disabled this.
     I am debuging the code and nagios spends a lot of time in the 
reaper event, as it should, I thik maybe this could benefit com a thread 
approach for this event.

     Tks.
