lat_fifo - FIFO benchmark
[ -P <parallelism>
] [ -W <warmups>
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
lmbench(8), lat_fcntl(8), lat_tcp(8), lat_udp(8), lat_unix(8).
