Hi, Although I can't comment on the sudden performance dropoff, I would like to point out that the numbers from the benchmark imply that the benchmark isn't using non-temporal loads and stores on either platform. The "it should just work" comment doesn't apply as it equates to driving a racecar with 6 gears and then never using anything higher than 5th in competition - because "it should just work". -Kip On 5/21/06, Attila Nagy <bra@fsn.hu> wrote: > Hello, > > On 2006. 05. 18. 19:19, Jason Evans wrote: > > The paper and slides for jemalloc that I presented at BSDcan 2006 are > > available at: > > http://people.freebsd.org/~jasone/jemalloc/bsdcan2006/ > > If you read only one or the other, choose the paper. > Thank you.
