four settings are effective on Windows
  1. tcp window size (Recv window 65535)
    [HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters \Interfaces \{Adapter-id}]
    TCPWindowSize = 17520
    .
  2. mtu size (use 1492, not 1500)
    Code:
    Network Type	MTU (bytes)	Details
Ethernet	  1500	 
IEEE              802.3/802.2	1492	 
PPPoE	          1492	        Optimal MTU for PPPoE over ATM is 1454
X.25	           576	        Dialup Connection
Ethernet (Jumbo)	         >=9000	Gigabit networking
    .
  3. ackdelay (see KB article)
    Note SMB Signing requires that SMB commands are processed synchronously, so a client is only allowed to send the next SMB command when it receives ACK of the previous one (Only one outstanding). This means that a client can max sent 5 SMB Commands/sec, as it has to wait for the Server's 200 ms ACK delay before it is allowed to sent the next SMB Command. This can cause very low performance when copying small files to a Server with SMB signing enabled (Imagine copying 1000 files of 1 Kbyte).
    .
  4. Selective acknowledgments (SACK) (described in RFC 2018)
    [HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \Tcpip \Parameters]
    SackOpts = 1 (Enabled = 1, Disabled = 0, Default = 1)
