[comp.sys.amiga.hardware] Aperf results on 3000???

Hi all.  I just ran Aperf0b and got the following results on an A3000.
I'm not sure I understand these results based on the documentation
found with the program.  Is there something wrong with my A3000 or the
program???

CPU: 68030 at 25.00 MHz
FPU: 68882r31 at 25.01 MHz
MMU: in 68030

MEMORY SPEED:  wr.L   wr.W   rd.L   rd.W

That's right on...

>FPU: 68882r31 at 25.01 MHz

The clock is 25.000000MHz, according to the crystal rating.

My guess is that this program doesn't know how to measure RAM speed in
actual Megabytes/second.  The relative measure against other systems may
have some validity, if the program was clever enough to make its test
independent of the speed the RAM's running out of.  Disable Fast RAM and 
see if the chip numbers come up the same.

That's correct default setting.
