We seem to have a misunderstaning, I didn't mean anything like that.

Say I install FreeBSD (using default partitions), install MySQL from
a package on the CD, run a stress test, collect numbers, then
repeat the process with a Linux installed over the previous FreeBSD
installation, and find out that FreeBSD allows the MySQL server
process 1/3 queries less, what (if anything) will be wrong in my
claim that MySQL/FreeBSD is slower than MySQL/Linux?
