You're hitting a cache blowout
Hi,
Im trying to benchmark DF with sysbench and got 2 issues:
The cpu and OLTP (using mysql) benchmarks are ridiculously slow. ie. with
one thread they take minutes to complete while on freebsd its a matter of
seconds. Can someone verify this? I dont know if its sysbench or DragonFly
bug.

However whats interesting is DF performance in the fileio/seqrd benchmark
with one thread. DF seems to be about 4 times slower. But when you add 2nd
thread it almost catches up with FBSD.

What parameters to sysbench are you using and is the data set being
tested large enough to blow
What parameters to sysbench are you using and is the data set being
tested large enough to blow out the system caches?
