This is the Amiga 3000 25 MHZ. running WB 1.3

EXEC reports a 68020 CPU and a 68881 Math Co-Processor 
Available memory is  1147 KBytes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ since this is an old program I don't
think it knows about an '030, and it has the memory wrong as well.


CPU Timings
Copy Blocks in CHIP memory is           206 ticks vs 621    301 %
Copy Blocks in FAST memory is           104 ticks vs 621    597 %
Move from register to CHIP memory is    171 ticks vs 855    500 %
Move from register to FAST memory is     99 ticks vs 855    863 %
Move from data reg to data reg is        69 ticks vs 476    689 %
Unsigned divide in data register is     184 ticks vs 1812   984 %
Unsigned multiply in data register is   130 ticks vs 856    658 %
Unsigned multiply in CHIP memory is     208 ticks vs 911    437 %
Unsigned multiply in FAST memory is     152 ticks vs 911    599 %
Stack manipulation ( MOVEM.L ) is       105 ticks vs 598    569 %


   Total percentage speed:   619 %
 

This is now running on A3000 25 MHZ running WB 2.0 beta.

^^^ again wrong.. I don't have the code to this to find out..why.

When I tested the A2500 with the '020 I got a 350% increse.  I could
not test it with the '030 in it as they had it being fixed.  

Thanks to John Sparks for sending this program to me.  If anyone 
else has any other benchmarks that they would like me to do send 
them to me and I'll do my best to get them done and post.
