Recently Parallels (Win7 Enterprise guest) have started being very sluggish - every mouse click, every scroll action, every keyboard input goes through a layer of syrup. Usable but frustratingly so.
As usual, the Parallels process in Yosemite sucks up about 50% CPU, without anything at all showing in Windows Task Manager. I found the following message in Console, though:
2015-03-31 09:36:51,000 kernel[0]: process prl_vm_app[4783] caught causing excessive wakeups. Observed wakeups rate (per sec): 1091; Maximum permitted wakeups rate (per sec): 150; Observation period: 300 seconds; Task lifetime number of wakeups: 354888595
That does sound not very optimal. Why is it there?
I also found a strange handle in Activity Monitor, represented more than one time for the Parallels Desktop process:
/Users/<user>/Library/Application Support/Google/Chrome/Default/Cookies
Why should Parallels care about my Chrome cookies?
