LAT_CONNECT(8)			    LMBENCH			LAT_CONNECT(8)

NAME
       lat_connect - measure interprocess connection latency via TCP/IP

SYNOPSIS
       lat_connect -s
       lat_connect  [ -P _parallelism_ ] [ -W _warmups_	] [ -N _repetitions_ ]
       hostname
       lat_connect -S hostname

DESCRIPTION
       lat_connect is a	client/server program that measures interprocess  con-
       nection latencies.   The	benchmark times	the creation and connection of
       an AF_INET (aka TCP/IP) socket to a remote server.  Care	is  take  that
       the  connection	time  does not include any other overhead, such	as the
       gethostbyname() or remote port lookups since these  add	more  overhead
       than the	connection establishment itself.

       lat_connect  has	 three	forms  of usage: as a server (-s), as a	client
       (lat_connect localhost),	and as a shutdown (lat_connect -S localhost).

OUTPUT
       The reported time is in microseconds per	connection.  Output format  is
       like so

       TCP/IP connection cost to localhost: 1006 microseconds
