700%, in terms of the number of jobs it can spawn, according to a
volunteer tester who reported in a few days ago.

It's actually a bit inaccurate to talk about percentages, since
most algorithms used in Nagios 4 are several orders of magnitude
faster than the ones in Nagios 3, and that means they'll scale a
lot better, but for very small installations you won't notice
much difference except a slightly lower load.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
