lat_fifo - FIFO benchmark
lat_ctx [ -P <parallelism> ] [ -W <warmups> ] [ -N <repetitions> ]
lat_fifo 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. The message is passed back and forth using FIFOs.
Funding for the development of this tool was provided by Sun
Microsystems Computer Corporation.
