    as some of you know, I just got a 2010 mini server. I'm very happy with it except for one thing. Some times, most of them, the dock gets sluggish, and the spaces animation too. I used to have the same problem on my late 2009 mini, but not as much as I am getting now. For example, if I turned the iTunes visualizer on, the graphics improved, and now, if I turn it on, they get worse. I am running it at the same monitor I used the old mini, at the same 1080p 60hz configuration.
    Now for the facts:
    -At the monitor menu, I see that his frequency is at 67.5hz.
    -When I first booted the 2010 mini, I finished the installation but the mini booted and I had to do it all again, like some kind of error ocurred and the instalation wasnt completed.So, could it be a vad installation ?
    -Could the snow leopard server be causing it ? One thing I noticed is that my kernel task is aways using 15%-30% of my processor, wich didnt happened in the old mini.
    -I use hdmi-dvi adaptor. Would be any diference in using mini displayport-dvi instead ? Or could the problem be my dvi cable anyhow ?

    So guys, could you give me a hand here ? When it ocurred in the 9400M, I assumed that the chip couldnt run 1080p well. But, isnt the 320M capable to run 1080p just fine ? I am getting angry with it.
    Thank you in advance.

    How much RAM is installed?

    What apps are running when this happens?

    4 gb ram.
    I use 4 spaces and leave a mail at the 1st, safari at the 2, iTunes at the 3rd and ical at the 4th.

    A clean install wouldn't hurt - I have not done one in years, so not sure it would help.

    You could create a new user and see what happens under that account.

    My kernel_task is 0.9-1.9%, but I am on 10.5.

    If you are running VMWare/VirtualBox/etc then 4GB might be tight, but with just those apps you should be fine.

    Nothing's wrong with my Mini (non server).
    I even managed to play Half-Life 2 on it too.

    Well, I forgot to tell that the kernel is using 73 threads all the time. Is that high ? Could it influence in graphic performance ?
    I am really confused about what is causing this problem. Either my monitor , OS X Server or my graphic chip ?

    And just a correction, my monitor frequency is 60hz and not 67.5hz as I said before.

    Any Ideas ?
