I am running MaxMSP 4.5.7 under MacOS X 10.3.8 on a G4/867 MHz

TiBook with 768 MB of RAM and a 100 GB/7200 rpm HDD.

I wanted to show someone the difference between the CPU

consumption showed in the DSP Status window and the

consumption showed by the "top" app in the terminal (which is

suppoed to include activity of the scheduler). I was quite

surprised to discover that with not a a single patch open and

audio off, MaxMSP was eating much CPU, with values evolving

randomly from almost 0 % to more than 70 %.

I have tried the following without any result :

- removing patches in the "extras" folder;

The problem remains also after reboot of the computer.

i think -but i'm unsure- that the peaks are not real pu uisage, but ghost peaks.

on my 1.5Ghz pb, idle max takes about 7%

Weird and huge CPU consumption with no patch open!
