Okay, I will bite on this!  Here are elapsed times in seconds for
the unpacking of a source archive on some representative machines.

MACHINE and OS				TIME in SEC
Cray YMP running NLTSS				40
Cray XMP4/16 running LTSS			5
SUN2/50 DISKLESS SUNOS 3.4			10.8
SUN3/50 DISKLESS SUNOS 4.0.1			6.9
SUN3 WITH DISK SUNOS 4.0.1			2.7

Which is the mainframe? Which would you rather compile and load a program on?
