1. By default, Windows in normal auto tuning level will use RWIN size of 256 bytes with a scale factor of 8. This value is not suitable for all routers and servers which does not support TCP scale factor, and continue to communicate with 65536 bytes (64kB). 64kB is the fixed default TCP receive buffer, and through autotuning it can scale up to 16 MB.
2. However, the TCP auto tuning feature may get things wrong sometimes. Instead of optimal true receive window size, incompatible and out of range RWIN size may be used. By default, Windows in normal auto tuning level will use RWIN size of 256 bytes with a scale factor of 8.
3. Oct 05, 2012  Then, the Receive Window Auto-Tuning feature adapts the receive window size of the ongoing transmission to take advantage of any unused bandwidth. While the feature may improve speed, in some cases it can also cause problems and slow down the network. To disable the feature, use this command: netsh interface tcp set global autotuning=disabled.
4. Receive-Side Scaling. The status should be disabled. Receive Window Auto-Tuning Level. The status should be disabled. Add-on Congestion Control Provider. The status should be none.
