I've added a fair bit of information on the Opteron HOWTO Wiki at:
http://hashmysql.org/index.php?title=Opteron_HOWTO
for using Fedora Core 3 with X86-64.
In my performance testing, I was finding that with so much RAM, everything
was coming from RAM anyway. RAID10 seemed to be most stable, and writeback
caching increased the speed by about 15% although I don't think I was really
able to max out the IO anyway.
Best regards,
Richard Dale.
