MSCP SCSI controller speed

[9000 VAX]

Hi list,
  After some non-sleeping nights the QBUS MSCP SCSI controller is now
usable except that it is still controlled by the PC. I installed
NetBSD 1.5.2 and ran "cp base.tgz /dev/null", and the speed tested was
840KB/s.  I am wondering how fast those commercial controllers are. I
would appreciate it if those of you who own those boards could let me
know. The design goal is to approach the fastest.
  Thank you.
