Hopefully, ISC will have enhanced support very soon.  Under other OS's where
enhanced support is done (i.e. Netware 3.1), performance has been roughly
30%-50% better.  It mostly depends on the drive you are using.  We used a
SCSI-2 version of the Wren VII drive.  If you are using a 296N, you would
not get any measurable performance gain.
