How to optimize the Vcache

[Doroteo]

Hi,
I need some configure details on Vcache. What is the work of this service. I had seen that the particular cache memory can be accessed to increase the system performance. Also how to access the second level cache. I did not know how to edit the registry file for accessing this option. What are the ill effects of the same on Windows. Thanks in advance.

When you access a file on your hard disk caching software makes a copy stored in the Vcache. When you want to use this file, your program will first search the vcache if a copy exists. If so, the application will use the copy in the vcache and not the existing file on disk, so access time is greatly reduced. This is what VCACHE do in your system.

Here is a solution which allows to reduce disk access by configuring the VCACHE. Click on start Menu then run type msconfig then OK. In the System Configuration Utility select the System.ini tab. Look in the window line [vcache], if it does not create it. Enter these parameters: Chunksize = 512, MinFileCache = * , Maxfilecache = * , * = 25% of RAM installed. For example for 64 Megs of ram do this operation: 64 x 1024 / 4 = 16384. It'll just reboot to confirm this setting.

By this you can allow Windows to use the entire cache second level L2 of your old processor (up to Pentium II). Everything depends on the amount of L2 cache (128, 256 or 512). Click on Start > Run > Regedit and then click on open the key named HKEY_LOCAL_MACHINE (Little Miss Cross left ok?) Then System \ CurrentControlSet \ Control \ SessionManager. Edit the Dword value year set to 200

Warning some bases were 2 keys SessionManager. The interest incorporates the following sub key AppPatch, CheckBadApps, CheckVerDLLs etc. Click the right mouse button on the key, go to New then Key. Name this Memory Management key and press. Now in the right window click the right button of the mouse: New, DWORD Value named as follows: SecondLevelDataCache then validate. Double click this value in the editor, type 200 in hexadecimal is 512 in decimal and then click OK. Restart your computer.

Before editing the cache level keys beware the DWORD value 200 is valid only for processors equipped with 512 K cache. CPU with 128K cache (like the celeron 1), the DWORD value is 80 or 128 in decimal. Finally the DWORD value is 100 or 256 in Decimal. Note that this trick also works for the Athlon (usually 512 K cache) and Duron (typically 256K cache). The Athlon XP would only 256KB of L2 cache, it is advisable to check quantity available before the turn, it can avoid problems! You can use AIDA32 which will show you how much your L2 cache.
