Re: Domino 8 compression

[Chris Whisonant <chris.whisonant@xxxxxxxxx>]

Although IFS doesn't compress well to tape anyway, it could be that it was
already doing some compression when writing the data to the drive. You'd
have to go into the media statistics in SST to see what kind of compression
ration you're getting currently.
