Care to give a brief run down of your setup?  My RAID 5 array is handicapped
by having more drives than IDE buses so my numbers pale in comparison:

   8regs     :  2034.000 MB/sec
   32regs    :  1230.400 MB/sec
   pIII_sse  :  2221.600 MB/sec
   pII_mmx   :  2004.800 MB/sec
   p5_mmx    :  1993.200 MB/sec

Or maybe I'm missing something else?
