    I'm told that my "PF Usage" is abnormally high, so I thought I'd come here to investigate it. My first question would be if it is too high, and second what I might do about it.

    Right now, with IE7 open (using two tabs), and my background programs running (totaling 41 processes and 447 threads), I have 732584 KB of physical memory available of 1047280. PF Usage is listed as 319 MB (328860 KB of Commit Charge, 2516712 K Limit, and 908748 Peak).

    If I open World of Warcraft, my Commit Charge goes to 706256 K, available physical memory goes to 276112 K. Excessive?

    The pagefile is just a virtual extension of physical memory written to the hard drive. Data in physical memory that is not likely to be needed quickly is paged out to the hard drive and the physical memory address space is yielded to data that is currently needed. Pagefile usage depends entirely on the workload.

    If you have several applications open and then toss in a game as well, Windows memory usage algorithms will start loading physical memory with the new apps requirements and paging out stale data to the hard drive. It will keep some physical memory free for immediate use.

    Sounds fine to me, unless you have specific symptoms I wouldn't spend any time worrying about it.

    It was suggested that the reason it takes me takes me 41 seconds to log out in WoW with a mod called Lootlink enabled, verses less than 4 seconds without it enabled, was because of the size of my PF usage. Says the mod's developer...
    Thus, here I am.

    Is your pagefile:

    1. Managed by Windows?
    2. Managed by you with minimum and maximum size limits?
    3. Managed by you with a fixed size?
    4. On the same partition as Windows?
    5. On a partition separate from Windows?
    6. On a dedicated partition (no other files or folders, just the pagefile)?

    All of these have an effect on pagefile efficiency. For example, a fragmented pagefile on the same fragmented partition with Windows is the least efficient of all.

    You might try using XP_PageFileMon and create a log of PF usage. You won't get accurate numbers from the Task Manager since it states potential instead of actual usage.

    Assuming I used it right...

    You can set it up so that it creates a log file and resords the PF usage at intervals. That kind of information is actually more useful than a snapshot of a particular time.

    I don't see an option to do that in that program. It just seems to want to spit out those snapshots when I run it.

    You're right. The option that you see on first run to create a log file should be chosen. Then, a scheduled task can be created to run the program at a chosen interval (30 minutes, for example) and that will give you a longitudinal perspective on the usage.
