Configuring TCP/IP for Maximum Performance

This section describes how to benchmark the TCP/IP throughput and how to set the TCP/IP hiwater marks for best performance.

  1. To benchmark the TCP/IP throughput, use the ndd command to configure the values of some of the TCP parameters for maximum performance.

  1. To set the TCP hiwater marks for maximum performance, type the following ndd commands:


    # ndd -set /dev/tcp tcp_xmit_hiwat 65535
    # ndd -set /dev/tcp tcp_recv_hiwat 65535
    # ndd -set /dev/tcp tcp_cwnd_max 65534
