Not much to do with your original message, but I too have a question
about benchmarks.
 
I'm running 2 megs, 1.5 on an insider board on an A1000.  With a 68010.
 
I have run 2 benchmark utilities.  One is called 'checkspeed', and one
is called 'si' (a cramden utility).
 
Well, here's what one reports:
 
                Amiga System Information 1.0
                  Gerald Brandt  21-Jul-88


EXEC reports a 68010 CPU
Available memory is   746 KBytes


CPU Timings
Copy Blocks in CHIP memory is           412 ticks vs 621    150 %
Copy Blocks in FAST memory is           388 ticks vs 621    160 %
Move from register to CHIP memory is    503 ticks vs 855    169 %
Move from register to FAST memory is    457 ticks vs 855    187 %
Move from data reg to data reg is       457 ticks vs 476    104 %
Unsigned divide in data register is    1566 ticks vs 1812   115 %
Unsigned multiply in data register is   823 ticks vs 856    104 %
Unsigned multiply in CHIP memory is     992 ticks vs 911     91 %
Unsigned multiply in FAST memory is     964 ticks vs 911     94 %
Stack manipulation ( MOVEM.L ) is       620 ticks vs 598     96 %


   Total percentage speed:   127 %

(The checkspeed output).  The si program gives my rating as 1.2 times
a standard A1000.
 
MY QUESTION IS THIS:
 
How much of this rather 'special' increase comes from my fast memory,
 and how much from the 68010.
 
If someone has an insider, or just a 68010, I could mail you the
utilities, if you could perform the benchmark, and get back to me.
