    So I got my 15" 2 GHz i7 MBP with the HR display last week and all in all I'm enjoying it. I have noticed one difference in RAM usage between that and my old 2008 uBody Macbook, more specifically kernel_task. Upon boot, looking at the kernel_task process in activity monitor, I'm using about 380 MB of memory which, although high, gets worse and approaches 500 - 600 MB of memory usage after using the computer for a few minutes.

    I've checked on a friends 13" 2011 MBP, and although the kernel_task was higher than on my 2008 MacBook, at around 280MB, it was still within fairly normal levels.

    Looking in your Activity Monitor, how much memory is kernel_task using? I'd love to find out if what I'm experiencing is uncommon or just something normal everyone is dealing with.

    Thanks

    Just booted up.

    With Parallels 6 running as well, kernel_task uses

    80 threads
    717.8MB RAM

    Seems a little bit high. How much ram do you have? 8gb? then dont worry:cool:

    After 1h33min safari/itunes/photoshop-usage my kernel_task process uses 384mb ram and 84 threads.

    Mbp 15" 2011 hires 2,0ghz 8gb ram 6750

    I am usually 450+...no idea how that 'ranks', if it can be ranked at all.

    Run the "sync" utility three times in a Terminal window! Make sure you have admin rights via:
    Code:
    sudo -s
    (type your password here)

    Code:
    sudo sync
    sudo sync
    sudo sync
    then run the "purge" utility one time:
    Code:
    sudo purge
    (this requires the dev tools-make sure you have the newest version for 64-Bit kernel support)

    This empties all unused RAM-caches. However, this does not help in the case of Safari 5.x.x. Restart Safari to free some RAM!
