NAME

       lat_unix - measure interprocess communication latency via UNIX sockets

SYNOPSIS

       lat_unix [ -m <message size> ] [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]

DESCRIPTION

       lat_unix  is  a  client/server program that measures interprocess communication latencies.  The benchmark
       passes a message back and forth between the two processes (this sort of benchmark is frequently  referred
       to as a ``hot potato'' benchmark).  No other work is done in the processes.

OUTPUT

       The  reported  time  is  in  microseconds  per  round trip and includes the total time, i.e., the context
       switching overhead is includeded.  Output format is like so

       AF_UNIX sock stream latency: 700 microseconds

ACKNOWLEDGEMENT

       Funding for the development of this tool was provided by Sun Microsystems Computer Corporation.
