When TCP/IP network activity is light, delays may be encountered with the default request buffer size (4356 decimal).

The range of this parameter is 512 - 65536 bytes. Testing has shown that, in most standard Ethernet environments, 14596 (decimal) is a better choice, if the memory is available. Edit:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters

and Add Value name SizReqBuf as a type REG_DWORD.

Restart the computer.
