Many thanks to the following people for their prompt and correct
instructions for tuning the TCP receive queue depth under OSF 3.0:

    Jari Tavi 24-Mar-1997 1221 <jpt_at_namix.ENET.dec.com>
    mogul_at_actitis.pa.dec.com (Jeffrey Mogul)
    Dejan Muhamedagic <muja_at_galeb.etf.bg.ac.yu>
    Scot Needy <scot_at_finch.engrs.infi.net>

All the necessary information can be found on the very useful web page:

    http://www.digital.com/info/internet/document/ias/tuning.html


The procedure for a pre-4.0 system is:

    # dbx -k /vmunix /dev/mem
    (dbx) p somaxconn
    8
    (dbx) assign somaxconn=1024
    1024
    (dbx) patch somaxconn=1024
    1024
    (dbx) q
    #

On 4.0 or later systems the tuning parameter is 'somaxconn' in
the socket subsystem, and can be set in /etc/sysconfigtab.

-Jeff
