Server and Client Network Optimization
1.1 Network Properties
1) Click the "Start" -> "Control Panel" -> "Network and Internet" -> "Network and Sharing Center" ->"Local Area Connection".
2) In the pop-up "Local Area Connection Status" dialogue box, click the "Properties" button (Figure 1‑1).
3) In the pop-up "Local Area Connection Properties" dialogue box, only retain the "Client for Microsoft Networks" and "Internet Protocol Version 4(TCP/IPv4)", and uninstall other services and protocols (Figure 1‑2).

6) Choose "connection speed and duplex mode" to "automatic inspection". Please refer to the following form for detailed settings.
TCP/IP partial load option
Partial load receiving ChecksumRxIp
Partial load receiving ChecksumRxTcp
Partial load conveying ChecksumTxTcp
Partial load TcpSegmentation
Partial load conveying ChecksumTxIP
We have created a video - "NIC Optimization" (start from about 05:44).
Note:Its enough to just disable flow control in NIC properties. But depending on requirement you can disable other options as mentioned above.
Note: Most of the modifications of network card properties are under the circumstance of diskless. If you can't modify the information in diskless situation, please try to modify with disks being attached. Besides, if you failed to disable flow control on the client side even with Super Client on Device Manager, we recommend modifying before uploading image. If you have multiple specs, you need to modify every network adapter before uploading image. If the network adapter type is the same, just need to disable the flow control once.
1.3 Network Teaming
If you have more than 1 NIC on the server, we recommend teaming them so you will get the maximum throughput from your server to clients. When teaming choose "Adaptive Load Balancing" to use all available network bandwidth,
