20% CPU time when idle

Hi,

I am using the final release of parallels. The activity monitor shows parallels using 20% of my CPU time whenever I have a program open. After booting windows xp, parallels is using around 5% of the CPU but when i load up a program such as google talk, parallels jumps up to a constant 20% CPU usage in the activity monitor but the windows task manage shows 0% cpu usage. I have disabled sound and usb support in parallels but still no change in cpu use. I also disabled virtue desktop but no change in cpu use. Any ideas?

I am running a MBP 2.0 with 2GB memory.

Thanks,
Tin
 
Tin,
So when you run the other program PD then becomes the background task, or is this another program winthin Windows?
I'm not too surprised that PD might take up at least some more when running as a background task just to keep windows happy, since this is when OSX might add a lot of overhead keeping PD and windows tasks running without allowing direct virtualization access to the CPU which it does when running in the foreground.
Its not intuitive at all but I'm not too surprised that this is the case.

Cheers,
Peter
 
I have the same with FC5. In final release Paralleles is running ~20% CPU where FC5 is running just in concole mode (inittab 3) and there is not transfers of anykind or code compiling etc? Why it is so high. top in FC5 reports 99.9-99.7% idle? Parallels developers any ideas?
 
There have been several discussions on this particular problem, such as in
http://forum.parallels.com/thread1608.html .

The problem in WIN98 VM was somehow solved in RC2, however that in Linux is still
not perfect. Even after HALTing the OS, the VM still consumes more than 25% of CPU load.

We would expect more tweeks in the next releases.
