Tools Center CPU usage is constantly too high

    I've migrated my Vista 32bit from a Toshiba Notebook to my MacBook Pro.
    Vista runs fine, but it is too slow. Parallels Tools Center has an average amount of more than 50% CPU usage.

    Does anyone have an idea?
    I'm using a MacBook pro 2,4GHz with 4 GB RAM.

    thanks in advance

    Mine isn't at 50%, but more 10-20% and I think that is still too high.

    Why is it taking up any cpu time? Should it use more/less in the different view modes?

    worse experience

    That's really bad.
    It's impossible to work with the virtaul machine, as well as with OSX, because Parallels is consuming 100% CPU in MAC OSX.
    The Graphical experience is really bad. I turned my Vista into Windows Standard theme, because even Vista basic had a bad experience. But, also Standard (very basic) is really bad.

    How much memory do you allocate to Vista VM?

    Try to disable DirectX support in Configuration - Video.

    Please provide me with additional information about your Mac OS X, version of Parallels (build number), version of Vista , your virtual machine size.

    Hi, disabling DirectX made it better, however, windows Vista (enterprie) is still slow.
    Here are my details:
    - MacBook Pro 2,4 GHz ,4GB RAM, 160GB HDD 5400rpm, OS X 10.4.10
    - Parallels 3.0 Build 4560
    - Windows Vista Enterprise english
    - associated 1500 MB
    - 64 MB video
    - 32 GB HDD

    I think that the video memory is toooo low.

    When I switch into coherence mode, vista doesn't show the mouse icon if it is in the "virtual" not shown windows background. I'm using a Microsoft presenter 8000 bluetooth mouse. It works fine as well in OSX as in Vista.

    I'm startin to dislike parallels because it doesn't work performant. I just wanted to use vista for the new Office 2007.

    I found this to be the case today as well. I haven't noticed it before, but today, while using Flex Builder 2.0 (which is Eclipse which is running on Java, so basically Java) I found that Parallels Tools Center was using upwards of 70%+ CPU time (looked to be basically using all idle time). I only had a single app up and running under Windows XP, Parallels 3.0 (whatever the latest build is, not counting betas, the Check for Updates Now reports that I'm up-to-date). I've got a 2GB MacBookPro from June 2006 (first rev of the MBPs), whatever the top-of-the-line was (17", etc.). I've got 1GB allocated to XP. All I've got running under Mac is MAMP (Apache/PHP/MySQL on localhost) and Firefox.

    I've not really experienced this before, when trying to work in FlexBuilder, just typing, there was a ton of delay everytime I would change focus or click the mouse... the Java process was definitely being starved by Parallels.

    I hope this doesn't continue!

    I had two WinXP images. One that was clone from the other. After upgradng to 5160, I noticed that the cloned image was running 100% CPU. From the TaskMgr, it was the ParallelToolCenter.exe.

    As it turns out, the first image do not have this problem. After reviewing what the difference, I find that this one settings - under the Shared Profile, turn off the Desktop as Desktop in Windows made all the differenace. The ParallelToolCenter.exe now is less than 2% and the overall WinXP is nice and quiet again. And because I am on MacBook, the fan don't scream its head off.

    CPU is pegged at 105%

    I have a very similar problem as described here, which is that Parallels is unusable since it pegs my CPU at 105% (literally, that's what it says in the Activity Monitor application. I have a MBP 15" with 3 gigs of RAM, and this issue happens with no other apps open, with a fresh restart, and allocating all the RAM to Parallels. I haven't tried some of the suggestions yet, but this problem was present for me in 2.0. I just upgraded to 3.0 and installed the latest build (5160.), so for me, it hasn't been build-specific.
