Optimise the Second Level Cache

Optimise the Second Level Cache Setting for Faster Data Transfers Your processors level 2 cache is a small amount of fast memory built in to the processor chip, which allows Windows to quickly transfer data between your PC's memory and CPU. To make this process efficient, Windows needs to know the size of the level 2 cache on your particular processor, and tries to discover it when your PC boots up by querying the Hardware Abstraction Layer (HAL). If your PC's hardware does not behave correctly, it is possible that the level 2 cache size will not be reported. When this happens, Windows uses a default value of 256K, which can mean data is transferred inefficiently, unnecessarily slowing down your PC. To get around the problem, you can set the size of the level 2 cache manually in the registry, to ensure that Windows is always using the most optimal settings. Check with your CPU's documentation to find the size of the level 2 cache, and then proceed as follows:-

1. Press [Windows Key] + [R], type REGEDIT and click OK. 2. Navigate to the registry key: - HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Control\Session Manager\Memory Management 3. In the right-hand panel, double-click on :- SecondLevelDataCache. 4. Change the Value data field to the size of your CPU's level 2 cache (in kilobytes), then click OK. Close the registry editor and reboot your PC for the changes to take effect
