To improve the performance, add UseSM and PagingEnable key to the Registry:

1. Open the Registry Editor and back your Registry.
2. Add UseSMDWORD key by:
   1. Locate and select HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSApiNt\Parameters.
   2. On the Edit menu, select New, and then select DWORD.
   3. Type "UseSM" as its name.
   4. Double-click UseSM, type "1" in the Value date box, and then click OK.

   This allows VsAPINt to use the system memory. In most system, especially in multi-processor system, the system performance could be better.

3. Add PagingEnable DWORD key by:
   1. Locate and select HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TmFilter\Parameters.
   2. On the Edit menu, select New, and then select DWORD.
   3. Type "PagingEnable" as its name.
   4. Double-click PagingEnable, type "0" in the Value date box, and then click OK.

   This is for pattern paging.

4. Reboot the machine.
5. Check if there is a change in performance.
