Thanks to reader, Olivia, who also recommends to turn off the paging file in not only the system properties, but also in the registry. I haven’t noticed any particular difference in performance after editing the registry, but I figure it couldn’t hurt. If anyone notices a difference, please let me know.
You should not disable the paging file if you have not upgraded the RAM to the 1.5G maximum. If the computer does not have enough available real memory and no virtual memory, the system will crash. However, if you have upgraded the RAM, turning off the paging file will make your netbook a bit faster. First turn off the paging file in the system. You can disable it in the control panel:
CONTROL PANEL > SYSTEM > SYSTEM >ADVANCED(tab) > PERFORMANCE(SETTINGS) > ADVANCED(tab) > VIRTUAL MEMORY(CHANGE)
Reader Olivia suggests to also turn off the paging file in the registry:
START > RUN > (type) REGEDIT
Follow the directory structure to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\DisablePagingExecutive
Double click DisablePagingExecutive
Set the value to be “1″
Restart your computer
Larry, a MS MCSA commented advising against doing this and explains in detail why.
There is a great deal of confusion on the internet regarding the pagefile and the “DisablePagingExecutive” registry entry. This article is as confused as any I have seen.
Disabling the pagefile will most certainly NOT prevent paging. It will probably increase it. Paging of program code, DLL’s etc., can not be prevented and does not use the pagefile. There is no need to copy this code to the pagefile as it can simply be reloaded from the original files. Disabling the pagefile only prevents paging of modified data. This unbalances the memory management system and will probably impair performance. In some cases this impairment can be severe.
The “DisablePagingExecutive” registry entry actually has nothing to do with the pagefile. This setting only effects paging of a small portion of the Kernel and this does not use the pagefile. By default Windows will keep frequently accessed portions of the kernel in RAM whenever possible. Only in the event of heavy memory load would it be paged out. Enabling the setting will force portions of the Kernel to remain in RAM at all times, even if they are rarely used. It is generally best to allow Windows to page as necessary and not impose arbitrary restrictions.
I would strongly urge all who read this not to make any changes in system settings unless you understand what they do. Doing this can cause serious problems as well as impairing performance. The internet is notorious for spreading misinformation. The descriptions of these settings is rarely adequate and is often wrong.
Unless you really understand a system setting and have a specific reason to change it – LEAVE IT ALONE.
Thanks Larry for taking the time to write and explain.
