Help for very bad perf for MySQL

[Albert Shih]

Hi all

I've already send a message. But I don't receive any answer :-(. I try again
and hope there more solution 

I've a bi-proc single core Xeon 3.2ghz with FreeBSD 6.2, I'm running Mysql
5.X on this server and the performance of MySQL is very bad. For some
complexe select I've got ~6secondes (on some basic Linux it's take 0.6
sec). And I think this is nothing about thead (that's mean I don't think
FreeBSD 7.0 can solve my problem) because it's just for one select.

The server have two SAS 10 000 tr/m disks.

Anyone have some advise to tunning FreeBSD or MySQL for increase the perf ?

Regards
