Several weeks ago I posted a short note giving some personal observations
about Gould UNIX systems.  Since then, I've had an opportunity to do some
very brief and informal (about two hours worth) testing on a 32/97 and I
thought I'd give a quick report of what I found.

I should say that since there seems to be ample evidence that the Gould
processors run as fast as Gould claims on a wide variety of applications,
my main interest was in finding anomalous data points.

Unfortunately, the dial-in line on the 32/97 I was using was extremely noisy
and I was able to transfer only some very short test programs to the 97.
Because of this, the bulk of my testing was done via standard programs.

The Gould system was a single processor 32/97 with 4M of physical memory
running Gould's "baseline 8.1" which is a 4.1c more or less.  The tests
were also run on a Vax-11/780 with 4M of physical memory running 4.2.  I
was on the only person on the 97; the Vax tests were run with a few other
users on.

In no particular order, here are some results that are representative of
what I found:  (Times are in seconds and are averaged over several runs.)

	nroff /usr/dict/words
		97:   31.6 user/  .8 system
		Vax: 140.2 user/ 5.0 system

	dd if=x of=y ibs=1  (where x is a 50kbyte file)
		97:  1.1 user/ 19.0 system
		Vax: 7.3 user/ 62.2 system
		
	gdata 10000 | cat | cat | cat >/dev/null (gdata 10000 generates 10000
						  50-character lines)
		97:  3.0 user/ 1.6 system
		Vax: 6.1 user/ 1.7 system
		
	fork 1000 (Does 1000 fork and waits of a child that dies first thing.)
		97:   .4 user/ 32.1 system
		Vax: 2.2 user/ 33.5 system
