As mentioned, a restore to /dev/null would be faster than a real restore
because metadata wouldn't be created.

Depending on the specifics, I might consider running a scanner >
/dev/null for troubleshooting (not benchmarking).  You get to see
Networker find the tape and pull the data off, but nothing else.  All
you're testing is the ability to pull data from the tape and hand it to
the scanner process.
