A very nice overview of tools, most of which I had not known, and most of which appear useful.

Shouldn't the number of minor page faults get smaller if I use MAP_POPULATE? I just tried it on one program, and got one additional minor page fault instead of the expected 50 less. If the number of minor page faults is not reduced, then MAP_POPULATE can only reduce major page faults (I have not tested that).
