I'm guessing if 100% usage in a dual G5 on Activity Monitor simply means that each processor is taking 100% or 50%. Also, sometimes CPU usage reach a 120% peak. At the moment I was unable to completly fill with green the two processor displays, and I was ripping a DVD, browsing etc... is there something wrong?

The system is a dual G5 with 1GB ram.

Thanx

Yup, if you think ripping a DVD and browsing the web is heavy enough use to max out both CPU's on a dual G5 you are crazy Just kidding. Nothing seems to be wrong and, yes , 100% corresponds to 1 CPU so 200% would be the max of both CPU's together. If you want to see both CPU's max out take 10 Quicktime movies and play them in a loop. Take another QT movie and drop it into iDVD so it starts encoding it in the background and then start scrubbing back and forth making the dock magnify really fast. If that doesn't quite do it try downloading Cinebench and run the benchmark and it will do tests that both max out one CPU and 2 CPU's as well. Grab the G5 version below the other OSX version. The dual tests come at the end of the single ones so you may need to wait to see the usage spike. http://www.maxon.de/index_e.html

Keep in mind that it is rare in normal usage to see both CPU's get pegged for any real amount of time. This is part of the beauty of a dual-CPU machine in that they generally stay very responsive no matter what you throw at them, almost always that is. Just think that if you see 120% usage at any one time, a single CPU machine would be probably sitting near 100% under the same conditions, struggling to keep up with all that's being thrown at it, while it is just a yawn for a dual machine

Thank you.
I'll stress cool: the system tonight.
