During Windows installation, Setup queries the system processor to determine the size of the Level 2 cache. However, it doesn't always succeed. When this happens, Setup configures a default setting of 256 KB in the registry.

If your computer has a larger Level 2 cache than Setup configured in the registry, your system won't perform optimally.

To significantly increase the performance of your system, change the value in the registry to match your Level 2 cache.

Here's how:

1. Launch the Registry Editor (Start>>Run>>Regedit.exe)

2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management.

3. Double-click SecondLevelDataCache DWORD value.

4. Using the options below, change the value in the Value Data text box
to a number that matches the size of your Level 2 cache. Then click OK.

Level 2 cache >>>> Value Data setting
256 KB >>>>>>>>> 0
512 KB >>>>>>>>> 200
1024 KB >>>>>>>> 400

5. Click OK and close the Registry Editor.

You will need to restart the system or log out of Windows XP for the change to take effect.
