That's not awful at all and can actually be quite normal. If all of your
checks are 10 pings for example, that would mean a 10 seconds average
execution time for example. That's acceptable and expected.

Latency is more concerning since it means that nagios isn't being
allowed to run checks when it's supposed to. This is most often caused
by a low max_concurrent_checks, regularly scheduled host checks or host
checks happening a lot in general.
