Important note, multiple CPU's will only help gzip if you are running
multiple gzip jobs at once.  gzip does not make use of multiple
processors.  Even then, I/O could quickly become a bottleneck.

For somewhat better compression, check out bzip2 which is almost (but
not quite) a drop-in replacement for gzip.

mgzip will make use of multiple CPU's, but initial tests show it doesn't
run any faster than gzip if you only have two processors.  If you're on
a 4-way or 8-way machine (or more) you may or may not see improved
backup performance.
