What kind of information do you have about average CPU load or I\O wait time? Whether Nagios is using ndoutils or not there will be a hardware limit as to how many disk writes it can handle in a given period of time. Even though you're only running a few active checks, it could be a symptom that your machine is having to wait on itself to write to disk for other things as well. The doc below is written for Nagios XI, but of a lot of the items apply to Core as well. I would consider exploring some options with a RAM disk in order to reduce disk activity.
