I think the parallelize_check directive for services is deprecated in Nagios 3.

Even if it does still work in version 3 Nagios, I would question
whether it is desireable to have Nagios not run any other checks at
all for ten whole seconds while one of these checks is run, especially
if there are quite a few of them.
