[comp.unix.ultrix] Streaming TU80 under 2.0

	(The other was a hope for performance throughput - does anyone know if
	2.0 will run faster (or slower) on a 750?  Is there any hope of getting
	the TU80 to stream, or at least move a bit faster?)

We're running Ultrix 2.0, and have been for about a month. (We started with
Ultrix 1.0 back when it was mostly vanilla 4.2BSD). The TU80 runs a _lot_
faster. Epochal backups that were taking six and a half to seven hours now
take two or two and a half hours. No kidding. The first time I saw it run
I thought it was doing a forward-space. I restored some files off the tape
just to make sure it was really writing to it.

As for performance, if you're running NFS at least (as we are) expect slower
performance. Noticably slower. Of course, we're running in only 5MB real,
which is the minimum you can run 2.0 in according to the release notes. We're
going to have to look at a memory upgrade. Sorry, no benchmarks for comparison.

The only thing that depreciates faster than a computer is fresh fruit.
