page file tweak

[31mojo]

here are a couple of tweaks for the paging file

Click on Start, Run. Type in regedit & hit Enter. Go to [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSessionManagerMemory Management]. You can edit the following entries as you see fit for your PC.

ClearPageFileAtShutdown.

For the more paranoid Users out there this option will be of some use. Right click on this entry & select Modify. A value of 1 specifies that the Pagefile(s) are to be wiped of content during the shut down process. This will result in system shut down times taking longer, although you can be confident that no data stored in it will be able to be accessed as a result (As it will be empty upon shutting down). Setting this to 0 will disable clearing the Pagefile(s) & result in fastest system shut down.

Disable Paging Executive.

Right click on this entry & select Modify. When set to 1 this disables pageable code (Drivers, executables, etc.) from being sent to the Pagefile, rather being kept in RAM instead. This can greatly improve performance given that RAM is a great deal faster than any Hard Drive. That said this requires a great deal of RAM installed to be of any benefit, as such I’d recommend leaving this set to 0 unless you have 256MB RAM or more.

Large System Cache.

This setting specifies whether or not the XP uses RAM less 4MB for disk caching purposes. This will be disabled by default. On PCs with a good deal of RAM (256MB or more preferably) installed setting this to 1 (enabled) should result in best system performance, although for those with less RAM available setting this to 0 will result in best overall performance. This is the same as the Memory usage option in System Properties.

IoPageLockLimit.

This DWORD value limits the maximum amount of kilobytes that can be locked for I/O operations. Right click on this setting & select Modify, then select the Decimal button. The default value for this is 512 & on some systems you may find increasing this value to improve system performance. The maximum value for this setting is RAM less pad. Pad being based on the amount of RAM installed in the system, e.g. Pad is around 64MB with 512MB RAM installed. This is a more useful setting if your system is used for file sharing, or server tasks.

PagingFiles.

This option contains the location of the Pagefile & the Initial & Maximum size values. This is useful should you wish to rename the Pagefile, e.g. pagefile.sys to win386.swp, to do so select this entry, Right click on it & select Modify.

hope you enjoy
