    Hey so i have a 2010 15" MBP 2.66 ghz i7, with 4 GB ddr3 1066 ram, 500 GB 7200 rpm HDD, and the nvidia GT 330 M gpu. I tend to get down around 30 MB of ram when i am running Starcraft 2.

    I do not understand what pages in and pages out means. Before i started SC 2 it was like 50k + pages in and 0 pages out. After running SC 2 for like2 hours i have 150k+ pages in and 100k + pages out.

    I am pretty sure i just need to add some more ram but i would like to know what these mean so i can better monitor my system.

    Thanks

    Mac OS X: Reading system memory usage in Activity Monitor


    Page ins and page outs - could somebody please explain this to me in idiot fashion?


    via "page in page out mac os x"


    It means more RAM might be needed, but SC2 is not able to address more, as it is a 32-bit application and thus limited to 2GB of addressable RAM.

    thanks for the links?

    so if i go from

    50 000 in / 0 out

    to

    150 000 in / 100 000 out when i play SC2

    would doubling my ram to 8 GB drastically reduce this number? (the outs)

    I doubt that, as SC2 can't address more than 2GB RAM, as it is a 32-bit application.

    Do those page outs worry you or hamper your game play extensively?

    My current readings, without playing SC2, but opening Windows via VM and using Avid Media Composer to log footage.
