Because ssh has way more overhead especially because of the way
how the ssl connection is handled. Therefor a check_by_ssh check
takes longer then a check_nrpe check. This _is_ significant if
you are running 2k checks per minute like me and some other people.
Lots of check_by_ssh checks slow down the machine by a big degree
and check latency will skyrocket.
