Is this an excessive number of Page-Ins/Outs

    In the past 3 hours of playing WoW on my G5 with 768MB DDR RAM, I have had:
    ~47,000 Page-Ins
    ~32,000 Page-Outs

    Is that excessive? I also get a high number when doing a lot of photo or video editing/encoding, etc.

    Would I be a lot better off with 1GB or 1.5GB of RAM, or are those numbers acceptable?

    Yeah, you'd notice quite an improvement with more RAM. As always, go with as much as you can afford/justify. :)

    RAM is like spinach. It's good for you. And the cost between adding 0.5 GB and adding 1 GB is not that much. Just hit that. :)

    i have a little question, with probably an obvious answer. how do you find out how many pages in/out you have. i know that it's probably obvious but i want to know and its probably so obvious that i overlooked it and couldn't figure it out.

    Applications -> Utilities -> Activity Monitor.

    It's listed at the bottom of the window.

    Not sure about this, but isn't there a ratio of one to the other? After 1 day and 9 hours of uptime, I have:

    159,931 Page In

    72,801 Page Out

    Is this normal?

    wow, so obvious and right in front of my nose. that was the first place i looked:eek: . I have alot of pages in/out on just safari/mail/ichat. 275,481 in and 314,192 out! that's not right. i always thought 512 ram would be good on a powerbook:eek:

    EDIT: and that is at less than 1.5 days. 1 day 11 hours.

    Depends on what you're doing. The number of Page Ins is not really a concern in most situations. Just Page Outs.

    This is 11 days of uptime on my iMac G5 2.0 / 1.5GB:

    71926 in / 2865 out

    This is 12 days of uptime on my iBook G4 800 / 640MB:

    2.1M in / 1.1M out

    :eek: :eek: :eek:

    Yankeefan, I don't think you'll see a small number of pageouts unless you have 1 GB or more in Tiger. Even in Panther, you had to get to at least 640 to not have excessive paging out, and really further north than that. It seems like you lose another ~128 MB with Tiger unless you disable a bunch of stuff. Your PB would run a lot better with more RAM.

    It does bear saying that my usage profile on my iBook is actually heavier than my iMac right now. But still....

    1GB really does help. In 12 days, I have:

    321,689 in
    89,206 out

    It really depends on what (RAM-hogging) apps you're running. I'm only into my 22nd hour, and I've acccumulated to over 83K page outs, even though I've got 1GB RAM....

    I would say you need more RAM, but I have 212585/223833 in/out's, and still running smooth. Next time I buy a new OS I'm creating a swap partition. :(

    Good analogy mkrishnan.

    Adding more RAM would be recommended! :)

    OR open terminal app & type in this command:

    top -u & press enter
    page ins & outs will be on the last line that starts with "VM", but above the running process list

    but in any case, if you have ANY page outs, you are regularly exceeding your installed ram, and this will not only cause system & app slowdowns, but also increase the wear & tear on your HDD too......

    So, MAX DA RAM :)

    After 18 days of heavy design work, with 2GB of ram, I have 182.3k page ins, but Ø PAGEOUTS :D

    How much RAM do you have, out of curiosity?

    I think that for most people, the additional cost in getting from a few hundred page-outs per day to absolute zero would probably not be worth it. But in your situation, I could certainly see that. I'm certainly not getting more RAM for my iMac because it has page-outs once in a while. :)

    The other thing to take into account is that your page-outs may spike when you do something unusual for your system. If you do that unusual thing once every two weeks, and are not bothered by the speed, and it creates a few thousand page-outs, but you otherwise don't get too many, then that's very different from having page-outs during every hour during the week, while you're using your computer for everyday things, whatever that means in a particular person's case.

    wont make any difference :)
    more REAL ram is the ONLY answer......

    alot of OS X users tried the swap thingy back in 10.1 & .2, and it helped a little, but back then, OS X didnt need 512-768MB all by iteslf either..... :D

    Get the extra RAM. I used to have a lot of page outs, but haven't had any in the two months since I upped the RAM in my iBook G4 to 1GB.

    answer: 2 GB.......

    and my wife uses every bit of it everyday in photoshop and other design apps, manipulating huge mega-GB files with mucho levels, layers, transitions, effects ect ect....... :) in addition to running the usual culprits like Camino, Mail, iTunes and Quicktime/VLC ect ect

    THIS is her normal everyday use :D

    Well my iBook is going on about 2 days now and i have 66,065 Page ins and 0 Page outs.

    I also have 1.5GB of Ram in the IBook.

    On my iMac with 1GB of ram i have 135,410 Page ins and 42,841 Page outs. This computer has been up for about 2 days and 12 hours

    Note bad at all. Ram is really the key and 1GB seems to do perfect for most users

    uummmmmm..............you appear to be contradicting yourself :)

    your iBook has 1.5GB & Ø pageouts, BUT
    your iMac has 1GB & 43k pageouts.....

    so it would appear that 1.5GB is the current sweet spot, yes ?

    Well the iMac gets used for a lot more heavy stuff then the iBook does. I do a a lot of home movie stuff for my mom and dad on the iMac. The iBook is basically a glorified homework typeing machine. I am pretty sure, and i think that most hear would agree, that 1GB of ram os the sweet spot if you dont do anything really heavy.

    I do like it when someone says something so bonkers it makes you wonder if they actually said that because your not that awake and was concentrating on something else at the time.

    Spinach.
