High Parallels CPU Usage

[koppah]

Parallels seems to have gone down in efficiency with the release of PD8. When Windows is using about 20% CPU usage overall, the actual Parallels host in OS X can easily be using between 100 and 200%. Any reason why there's so much overhead...?

Currently, my total Windows CPU usage is hovering around 20%, but Parallels is at 150%.

Parallels support cannot solve this problem of high CPU usage.

I had a senior support rep take control of my MacBook Pro for 65 minutes after a lower level rep gave up. The senior level fixed the issue for about 6 hours. Now it's back again.

Very disappointing that Parallels does not have the integrity to admit that this is an issue and work towards a solution.
