  1. Thats Nice to hear about good pagefile optimization comments . but there is one more thing consider page file in windows xp . Windows Xp Pages its Some of Process By default . It is Necessory to Mention about how to disable that if you have more than 512 mb of ram .

  2. This does not entirely makes sense.

    Say you have a newer system with 2/4/8gb of ram (which many these days do) are you saying that 16gb of page file is necessary?
    Even with my own experimentation I have found that excessively large min sizes causes excess HDD activity, and that an ultra-low min is good to keep things faster.

    On my current system the best I could manage was a 100-2000mb file located on a separate partition on my OS install drive, and a 100-4000mb file on an independent partition on an independent HDD. This gives me blisteringly fast startup times, and relatively fast OS operation. The only downside is that, when running very large games, many files are paged to the second HDD, and the OS has a hard time on termination of the game as there are large amounts of data that have to be erased and re written across separate drives.

    However I wonder if this is still not faster overall than a single file on the OS install drive.

    Aren\’t there any better page file guides than this??? RAM x3 formula sucks, there is so much much much more that can be played around with to get page files working faster.

  3. can any body give answer for these ( swaping is part of virtual memory or physical memory)

  4. YOU HAVE GOT SOME KIND OF CLASS IN THIS SITE. Good to see you up and around!

  5. good info as for Disable mic say no i have 1 PC with XP & 2000MB Ram Page off it say 500mb some times will go to 1300mb set at 4000mb Page file 2 Hard disks Page on #2 fat 16 * 4000mb just for Page file only. looks like more ram window just take it all & go look for more. you can change settihg in reg to help it used ram still like page fist Hard drive min is 2mb for event viewer
    with this pc Page file is set min 500mb max 4000mb as for PC with 512 mb I now set to 1536 mb.

  6. i have 256 mb DDR2 533 Mhz ram. I am going to add 512 mb ram to it. my current initial size is 336 mb and maximum size is 672 mb in custom size in virtual memory dialog box. To which value should i set it now and after buying 512 mb ram? please help.

  7. I have an Athlon XP 64 3200+ (2.21Ghz) 1GB DDR2 system memory. I\’ve been having a lot of memory crash dumps. I\’ve read several forum postings on people who have at least 1GB of RAM disabling the paging file. I\’m clueless when it comes to system type optimization. If I disable the paging file, would have fix the system crash dumps I\’ve been having? Any comments or replies would be appreciated. Thanks.

  8. There is no fixed rule for the optimum value for pagefile minimum size. Setting it at 3 times the size of physical memory may not be enough if memory is short. On the other hand this may be far more than needed if you have 2GB or more. The optimum can only be found through experience with your own memory needs. The optimum will be somewhat above what will meet normal requirements. Windows will give warnings when this lower limit is exceeded. On no account should the minimum be lower than the size of physical memory.

    There is no need to set the upper and lower limits the same. By deafult Windows uses a semi-fixed pagefile. The lower value should be sufficient for normal needs while the upper should be much higher to handle unusual cases or you have set the lower value too low. Unless the lower value is exceeded there will be no pagefile resizing and no pagefile fragmentation. If the lower value is properly chosen this will not happen very often. Setting the lower and upper values the same will risk setting it to small or waste a great deal of disk spce.

    Pagefile fragmentation is not a serious performance issue except in extreme cases. Unlike many other files, the pagefile is not read serially. The pagefile is normally read in realtively small chunks and mixed with other file accesses.
