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
