Parallels slows down to a VERY slooow crawl

After moving from parallels 3 to 4 I've been having speed problems. After running parallels for a couple days, it will slow down to the point that a 10 seconds operation takes 20 minutes. Not kidding. Even after closing all other mac applications it does not change. No CPU load either (parallesl is taking 10%). I have to reboot parallels to fix.

Any way to fix this with reverting to parallels 3?

 

Hello,

Please follow the steps mentioned in the below article :

I looked at the link.

boot time is not the problem. It is after it has run for a long time

 

Am I really expected to boot up the VM and leave it alone for an hour before I start using it?

This is incredibly frustrating. If you don't have a working solution, can you at least come up with a timetable for when you'll get one?

 

I'm having the same issue here. At start, parallels page-in the whole virtual memory taken by prl_vm_app. As time passes, it starts to page-out. I don't know what's the matter with that, I'm afraid you need to use an special heap alloc from Mac OS X api to avoid it to be paged in/out. That's something you absolutely have to work on.
