    A couple of days after installing lion my fans started to rev up to 6,000rpm even when nothing was open. I opened Activity Monitor to find that the Dock was using 90-150% of the CPU!

    I don't have Parallels installed.

    Can anyone help me?

    same

    I have the same problem. I notice the Dock uses a lot of CPU when ever my mbp wakes up from sleep. Killing the process tends to fix it.

    mine is a 2006 MacBook and has the same problem. Video streaming is unacceptable.

    Sometimes even using Lightroom and iTunes makes the sound to stop or skip

    open activity monitor and select " all process" and verify which process is causing the problem. Citirx is one of the know culprit as far as i know

    Same problem here

    I have the same problem as well. Dock started acting weird after I installed Lion. I saw the issues with Parallel on other forums but I don't have any Parallel but VMWare. However, VMWare does not use any Dock feature (as far as I know).

    Anybody has found anything yet?

    For me, upgrading to Lion was a big mistake. It turned out to be the next Vista on Apple's corner. I stopped using Mail due to so many crashes. My Macbook Pro, Core 2 Duo, turned to a netbook. I noticed I started spending more time on my Windows laptop at work recently.

    Please help. I don't want to go there.

    In my case the problems was that Office 2011 spotlight plugin caused high cpu usage.
