Here is a full set of numbers for sloppy and tasklist. The sloppy version
is 2.6.9-rc2-bk14 with the prefault patch also applied and the tasklist
version is 2.6.9-rc2-bk12 w/o prefault (you can get the numbers of
2.6.9-rc2-bk12 w prefault in the post titled "anticipatory prefaulting
in the page fault handler")). Even with this handicap
tasklist is still slightly better! I would expect tasklist to increase in
importance for combination patches which increase the fault rate even
more. The tasklist is likely to be unavoidable once I get the prezeroing
patch debugged and integrated which should at least give us a peak pulse
performance for page faults > 5 mio faults /sec.
I was not also able to get the high numbers of > 3 mio faults with atomic
rss + prefaulting but was able to get that with tasklist + prefault. The
atomic version shares the locality problems with the sloppy approach.
