It depends on what you're doing with the system.  If you're just doing
plain selects and inserts, then mysqld is going to be I/O bound and it
doesn't matter what OS you run it on.  If you're selecting a million
records, doing group-bys or sorts, *AND* are doing two or more of those
queries at once, then you need a threads package that can use both CPUs
and will probably have to go Linux.
