	Ali Ozer recently posted some Dhrystone Benchmark results for the
Atari 520ST and the Amiga.  He requested that someone with a Turbo-Amiga
also run the Dhrystone and I said that I would, and I will --- I couldn't find
my old copy of the Dhrystone program, but I'm getting another copy today.

	The Atari 520ST Dhrystone results were interesting to me because
they show that the software can really make a huge difference in the 
performance of the system.  There is nearly a factor of 2.5 in the performance
of Lattice C V3.03 ( 450 Dhrystones/sec ) as compared to Megamax C V1.0
( 1136 Dhrystones/sec ).  Does anyone know why there is such a great variation
in performance?  Can we expect to see this type of performance variation on
the Amiga and Turbo-Amiga?  When I run the Dhrystone on the Turbo-Amiga with
Lattice C and find (hopefully) that it clocks in at 2500 Dhrystones/sec am
I, based on the Atari results, to expect that it really should be clocking
in at 6250 Dhyrstones/sec with a 'good' compiler?   

	I'd really like to get a handle on the real performance capabilities
of the Amiga, so in addition to Ali's request would someone run the Dhrystone
on the latest version of Lattice C ( and V3.03, V3.02 )? 

	Does anyone know if there are versions of the Dhrystone program
for Modula-2 and Fortran?  

	Al Aburto
