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
