Oh stop boasting. Grin.

Hate to say it, but I assume that you are talking about a 
PCI based Linux machine?

Maybe the peak performance is only really achieved when you have
a nice big SGI server :-)
Of course THEN you need the fibre channel models. Grin again.


Guess I'd start by looking at your SCSI controller.
Is there anything in the READMEs in 
 /usr/src/linux/drivers/scsi
about tweaking it?
