I kind of lost track of this thread and missed any useful performance 
information if you posted it.  Is this the same machine that has 
mysterious crashes?  If so, I would just give up, or replace the RAM and 
power supply and then give up.

Performance wise, what kind of load does it have?  Most servers that 
aren't doing graphics or number crunching are limited by disk i/o, not 
cpu so the disks and controllers are the interesting things to compare 
although if the controller requires a lot of CPU intervention (ide, sata 
in some modes) it may look like a cpu problem.
