This shouldn't be an issue. I have a very similar setup, 5 data
collectors reporting 3646 total services to 2 central hosts  

Verify that you have command_check_interval in nagios.cfg set to a
reasonable number (I use -1). 

Verify that your host check command is reasonable and exits quickly
(i.e. a single ping is usually sufficient). I personally don't use host
checks at all due to the volatility of the devices I'm monitoring.

aggregate_status_updates set to 1 may help, status_update_interval is 15
here.

Verify that your hardware (specifically drives) are operating correctly
and aren't starving for resources (cpu, memory, etc). I had a similar
problem once caused by bad writes to a drive in a hardware mirror. The
drive didn't fail out but the performance was miserable.
