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
