I understand your position, and felt the same way myself after reading some of
the comments made about previous OS-9 defragmentation programs. Speedisk
defragments at about one megabyte a minute.  So, a 20 meg disk is about 20
minutes, etc.  It actually is a little faster than that in practise.  Steve
Wegert says it takes about 40 minutes to defrag his 120 Meg drive which is
about 80 percent full.

Yeah, like automatically placing executable first in any directory list for
faster access, moving bootfiles to the end of the disk, moving all directories
to the beginning of the disk, as well as some features to be able to recover
from a crash during optimization without loosing the disk structure.
