Compression of data before transmission. Unless you
have a *very* overloaded network, or very limited tape resources,
the loss of speed due to compression is a serious consideration.
In the case of Macintoshes, ADSM is almost unusable if
compression is enabled -- throughput on an SE-class machine drops
to less than 15K/sec (compared to 115K/sec without compression on
the same machine).
Tapes are _really_ cheap compared to the performance loss.
One general performance note: Set the TCPBUFFSIZE value and
TCPWINDOW values as high as you possibly can -- if you have the
memory, the throughput improvement is fantastic!
