When using the "Advanced" menu, you  can select between compression
"off" , "save time", and "save disks".  In "save time" it only compresses
when there is time available.  "save time" is also the default.
On a slow machine (like a PC/XT) it essentually will not compress at all
in this setting.  "save disks" gives maximum compression.  On a fast machine
(such as an 80386), "save disks" can actually save time by requiring fewer
disk changes!  On ATs or greater, I always use "save disks".  On my old "XT"
compatible, I went back to the original Fastback -- it's faster!
