I recently downloaded a program called MacSpeed from *.binaries It is a
neat tool to get an arbitrary idea of where your macintosh lies in the realm of
performance, and I do not know exactly what parameters it uses. However, to
answer lots of questions about the 030 and its speed, I have a 20MHZ Dove
acclerator for my MacII. It has a hardware specific cdev that controls the
caches of the 030. I think the following will tell all:
CPU Disk Math Overall(times over an SE-20)
Stock MacII: 3.18 1.46 6.60 2.70
Souped up*: 4.34 8.69 31.65 6.63
*, no data cache: 3.70 7.42 28.55 5.66
*With both 030-20MHz caches, ramdisk(100ns ram), Radius Init (sane changed)
I only turned the data cache off on the third run. Obvioulsy,it affects disk IO
somehow. I got the stock numbers from the application, as it prints them as a
default when you start the test. A ramdisk really soups up the overall side,
and the math helps, but not nearly in a linear fashion. I welcome any data on
other macs, the Levco board, the IIx and SE-030 would be interesting to see.
Scott Berfield wrote the application. The instruction cache was always "on.
Any opinions above are just my own, and all standard disclaimers apply.
