    Hi there.

    I'm new here. I was hoping someone could help me.

    I have a Macbook Pro, details are:
    Lion 10.7.2, 2 Ghz Intel Core i7, 4 Gb 1333 Mhz DDR3 etc.
    I'm also using boot camp to run 64bit windows 7 on a partitioned 500GB (250/250) Hard drive.

    I have next to no documents or files on my mac, but while i'm typing i get little freezes or pauses and the "rainbow pinwheel thing" appears for 2-3 seconds and anything i've typed doesn't appear, but then when the pinwheel goes back to being a mouse pointer, the text i've typed catches up with itself.
    Its just plain annoying and seems to happen all too often. Even whilst writing this.
    Another thing is while it freezes/pauses for those few seconds, my music on iTunes stops while its in that state, then starts playing again when it catches up with itself...

    I'm a bit rubbish at explaining it, i hope you get a rough idea.

    Any tips would be great, i'm stumped.... Normally i would of thought it was a lack or memory/slow disk or something, but i can't see any reasoning for it.

    I look forwards to your replies.

    Looks like some program is consuming all of your resources. Given your MBP specs, you should not be running into any trouble for your MAC applications.

    To see what is going on, I would recommend opening up a terminal and running the "top" command. This should show you what processes are running and what is taking up your CPU. Please tell us if you can see any problems on it.

    Thanks for your response.

    I don't see anything unusual. This is whats it displayed:

    Obviously, they change every second or so, (including the processes stats) but this gives an idea....

    Does anything look out of the ordinary to you?
    Thanks.

    Hi people :D

    What are the normal stats of the Kernal Task in the Activity Monitor?
    Mine seem abnormally high, but this might be normal.

    Thanks.

    It depends on what you have running. Launch Activity Monitor and change "My Processes" at the top to "All Processes", then click on the CPU column heading once or twice, so the arrow points downward (highest values on top). Also, click on the System Memory tab at the bottom. Then take a screen shot, scroll down to see the rest of the list, take another screen shot and post them.

    I just did a software update, and now the stats have dropped significantly.
    It was using around 7-8% CPU / 144 threads and 600mb real memory...

    I would still appreciate your thoughts. Thanks for commenting.

    I don't see anything out of the ordinary in what you posted. Just keep an eye on things for a while. If you see performance slipping again, launch Activity Monitor and always make sure it shows All Processes. If you have an app that's causing problems, you should be able to catch it.

    This all looks very normal, not big issues. Just out of curiosity, are you running boot camp when you took this data?

    If you just did a software update it may be indexing spotlight and that would cause a performance hit.

    It's not indexing, as evidenced by the Spotlight Menu Bar icon not having the pulsing dot in the center, as well as the fact that the mds and mdworker processes are using very little CPU and RAM. That's one of the first things I usually look for. Also, Software Updates don't usually trigger reindexing.
