Large disk Caching

[Admiral Huddy]

I've just read an arcticle that says the XP defaults disk caching to 4mb..

Apparantly, to change this you need to change the large memory caching registry in the following hive:

HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\CONTROL|SESSIONMANAGER\MEMORYMANAGEMENT

Look for the LargeSystemCache entry. The dafault for this is 0 which is off.

When enabled, this takes ALL memory not being used by applications, system or data and uses for caching.

Now am I confused here. Does this have anything to do with the build in cache in the hard disk.. My HD is 16mb. Does this mean that only 4mb is being used and i have to set this to Enabled?

Has anyone set this to 1 - enabled?

Nothing to do with hard disk's built in cache. The system cache simply uses RAM to store I/O transactions.

LargeSystemCache setting is nothing secret, it is exposed in Control Panel->System->Advanced->Performance->Background services as a check box. It should only be used on servers that don't do a lot of desktop activity.

Thanks for clearing that NathanE..
