Hi Kris,

Show your kernel config etc.
I've been working with Steve on this project. We've been playing
with various tuning factors, including kernel changes, different
stripe sizes on the RAID, my.cnf tuning, libmap.conf, and although
we can gain a bit here and there, we can't account for the doubling
of performance with Gentoo. Anyway, I've included the dmesg and
kernel config.
The Gentoo install was pretty vanilla-flavoured, as neither Steve or
I had installed Gentoo before, and both of us are pretty rusty on any
form of Linux.
Incidentally, this does not seem to be I/O-bound. The data is big
enough to stay in the table cache anyway.
I just noticed these particular tests were done on FreeBSD without
HTT, whereas the Gentoo test was. However, I can tell you that in
earlier runs, the difference between HTT and non-HTT on FreeBSD for
this benchmark was negligible.
Regards,
Tom
