• Activate support for Explicit Congestion Notification (ECN)

  Explicit Congestion Notification improves congestion handling for the TCP/IP protocol.

• Compound TCP (CTCP) can speed up TCP Slow Start

  Compound TCP (CTCP) can improve the throughput for high bandwidth and high latency connections, by improving TCP slow start.

• Configure TCPIP Max Transfer Unit (MTU) size

  Changing the Max Transfer Unit (MTU) to avoid packet fragmentation and connection loss.

• Configure initial congestion window to speed up TCP slow start

  Description of how TCP slow start can introduce latency for short living and long living TCP connections.

• Disable IPv6 imaginary tunnel network interfaces

  IPv6 network tunnel interfaces makes you open for network attacks, and introduces an overhead.

• NDIS 6 hardware features that increases network performance

  Windows can activate NDIS 6 network hardware features for offloading the system processor.

• TCP/IP RWIN Auto-Tuning can slow down network

  Not all network routers supports the tcpip receive window scaling flag used by Windows Vista.

• The TCPIP nagle algorithm can slow down network

  Description of the nagle algorithm effects on the network throughput, and how to configure the delayed ACK.

• Turn a computer into a WIFI hotspot

  How to create a wireless network between two computers without needing a wireless router.
