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
       connection 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
