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.
