Hi Jeff,

Thanks.  Turning off the drive's compression probably won't gain me a lot, but I'll give it a try.

Dave,

OPTI-TAPE virtual tape volumes are normally compressed. This type of data
will not allow the drive to compress it. At leaat not very well. This may
explain what you are seeing.

Regards
Jeff
