Well, I would think some here would be interested in samba performance.
However, If 4-way P4 systems are considered rare at this point I guess it's
not important enough to revert. FYI, after testing 2P with and without
hyperthreading, it's much faster. 481 Mbps for no hyperthreading and 605
Mbps with. If I can get even close to that improvement with 4 processors,
I'll be very happy.
