Hi, I'm having this problem across the board - both Windows XP and CentOs 4.4. Even when idle on a command-line only installation, Parallels desktop consumes 44% processor usage on my Macbook Pro's Core 2 Duo. The same happens with Windows XP. This was a problem with the beta (build 3036), where processor usage on an idle CentOs 4.4 was usually around 15%, but it was nowhere near as bad as this. Was there a regression? Anybody have any pointers on how to fix this?
