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.
One thing more...
I've seen a message on a PostgreSQL list that MySQL can
_silently_ change the type of the tables if it cannot find
some library. Check that you have really same DBs
in Gentoo and FreeBSD.
