    I am trying to better understand this term I have heard mentioned here and there on the forum with regards to Page ins and Page out's - what does the page ins and outs do exactly?

    I run alot of video through my MBP and during a video I did today here is what I got on the activity monitor.

    Free: 15.0 MB VM size: 186.30 MB
    Wired: 1.24 GB Page ins: 459.8 MB
    Active: 3.97 GB Page outs: 15.7 MB
    Inactive: 2.77 GB Swap used: 31.1 MB
    Used: 7.98 GB

    I would love to get a better translation of what this all means... and how it is taxing the system.

    I have seen this on Wikipedia and am still a bit confused as to how the paging thing relates to the situation I have, thus the question for someone that has an intimate knowledge to break it down to something easy for a neophyte like me to grasp.

    Thanks for adding this link to the thread, it is helpful to the overall question.


    Thanks for this link GGJ, this has helped me get a little greater grasp in understanding the Page in and outs.
