I feel this is a good tweak.

Try inWindows Server Service (Windows XP, Vista and Server 2000, 2003)

This setting in your registry allows for the optimization of memory, network or to balance these two.

Click on start type ‘regedit’

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver


Create a new DWORD value, or modify the existing value, named “Size”.

Change the value to 1 for memory
Change the value to 2 for balanced
Change the value to 3 for network throughput

Exit the registry

Reboot your computer

Enjoy,,,
