Weird SYSInfo Readings - Help
« on: May 28, 2008, 10:02:40 PM »
I tried to run sysinfo on an extra A4000D that I had stored away and for some reason it shows the Dhrystones at about half the speed of what an A4000 with A3640 should be.  Does anybody have an idea of what is going on?  I am running OS3.9 with both BB's.  I later ran another Sys monitor program that tested more things and it showed the same low readings.

I ran sysinfo again and it said the Icache was on and the Dcache was off.  I changed the Dcache to on in the program and rerun the speed test and the dhrystones had increased from about half of what they should have been to 3/4 of what they should be so that helped some.  I have just never had a problem like this before.  The sysinfo has always read what I knew to be the speed of the computer.  Sysinfo shows that the Cback is off and that won't change.  It also shows that the mmu and fpu are both not in use.

Check the 68040.library, without it 040 copyback cache cannot be enabled and you get poor system performance.

As is always the case, Piru was right.  I replaced the 68040.library with the one from OS3.1 and immediatly everything was running and reading correctly.  Thank you so much for the help.  My last question would be what would be the best 68040.library to use?  I am assuming there may be a better one than the one from the OS3.1 disk.

Check out this thread.

There are newer 68040.library(s) is it possible that yours had become corrupt. I'd rename it .old and copy over the latest one from 3.9. Then check sysinfo again. Also read the thread and talk to Gulliver to see which one he found that was best.

I'd say unless if you have any pressing needs for specific 68040.library version, use the CBM one.
