Step 4: Optimize the network and transport layers
Depending on the results produced in steps 1, 2, and 3, optimize the network and transport layers.
Optimizing the network and transport layers, may include, but is not limited to, these
recommendations:
Isolate any unnecessary TCP/IP traffic from the network.
Choose smaller packets to reduce transit times through intermediate networking
devices, as most of these devices are store-and-forward.
Increase the TCP/IP responsiveness to incoming/outgoing traffic by choosing
appropriate values for various TCP/IP timers, such as the retransmission timer, the
gratuitous ARP timer, the delayed acknowledgment timer, or by using the nodelay
option in conjunction with TCP sockets.
Avoid the use of time-consuming encryption facilities.
