To those wanting to hear of comparisons between various Prologs
the Digital Computing Lab at U of Illinois/Urbana
has several systems. The following figures are by courtesy
of Scott Renner. They apply to a quicksort of 30 elements.

Ident	  	Machine		Loading system		Execute program
		 	 	  & program

Edinburgh  	DEC-10		1.3 sec   35 Kb		1.2 sec	  47 Kb
Waterloo   	VAX		0.7 sec   17 Kb		0.6 sec	  24 Kb
Micro-Prolog	Z-80		10-12 sec 15 Kb		2.9 sec   28 Kb
Belgian 	CYBER 		0.08 sec  21 Kb		1.4 sec	  21 Kb
CProlog		VAX		1.8 sec	  21 Kb		0.7 sec	  25 Kb

And for those interested in the debate over relative speeds of
compiled LISP vs compiled Prolog, there is a paper in the 1982
ACM Symposium on LISP and Functional Programming which presents
evidence that compiled LISP is frequently twice as fast as compiled
Prolog !!
