	Well here are the sun figures I have found using the same
benchmarks as Dave.

	Machine		Dhrystones/sec	  
	 Sparc SLC	  10000
	 Sparc 2	  25000
	 Sun 3/60	   3333

	Sorry, can't seem to find a sparc 1 to try :-(  I'm not sure
whether SLC's are sparc 1 or 2 but I could find out if pushed.  The
sparc station 2 figures were obtained on a Sparc 2 with 64Mb of ram and
100Mb of local swap space and just a tad more expensive than a 540 :-) 
The sparc 2 also had 8 users on it.  So all in all not a bad performance.
	I'd say that Dave's 8000 for a sparc 1 looks about right to me
judging by the SLC figure I gave.
