I have the original 8-way intel Mac Pro. Under Tiger, everything ran fine with 5.10.41. All 8 CPUs were at 100%, and nice showed correctly.

Today I did a clean wipe/install of Leopard. Now BOINC tasks show as user, instead of nice. If I read an earlier post in this thread correctly, that is a problem with Activity Monitor and/or MenuMeters. Fine. Annoying, but letting it go for now.

The really troubling problem that I am seeing is total CPU usage. Under Tiger, MenuMeters showed all 8 as 100% pegged, all the time. Now, the individual graphs are all jagged with peaks and valleys, and when I set it to "show average for multiple processors a single display" (similar to the way that windows does it) it is showing only about 80% usage. Top shows about 80% as well. A snapshot of the Activity Monitor is on my downloads page.

I just lost 20% of my crunching power! Help!

Do you have a snapshot running under Tiger for comparison? I'm wondering if Tiger gave each process more memory.

If we can't trace a specific cause, then it would probably be a Leopard kernel glitch. Someone would need to report the bug, then you'd have to fall back to Tiger until a point update comes out to fix it.

No, no snapshot from before the OS change. FWIW, I have 2gb memory still unused.

I thought maybe it was throttling due to heat. I installed smcfancontrol, cranked up the fans, dropped the temp 15 deg C, but no change. I checked for dust bunnies too.

You still using 10.1 or the updated 10.2?

The update from 10.5.1 to 10.5.2 today helped quite a bit! I went from 80% to the high 90s. That was a nice surprise. But still not 100%.

I see you crunch WCG. Can you let me know if you experience any problems with 10.2? I tried leopard when it came out and had errors so went back to tiger. Once my WU's finish in a couple weeks, I'll try leopard. BTW, I looked at your web site and saw all the different projects your crunching. How many computers are you running (if you don't mind me asking)? Your electric bill must be high.

10.2? I guess you mean 10.5.2. So far so good. But I've only crunched a couple tasks so far.

Heh. That is just a list of ALL projects. I don't crunch for them all. In fact the ones in red, no one can. If you look at my stats, you will see what I am crunching lately.

And YES. It's damn high.

But a worth addiction. Hopefully, I'll be adding another mac pro by the end of the year. Don't care for alot of computers to clutter the room. Just more cores.
