-// Benchmark to measure throughput performance piping an input stream to an output stream.
-// This allows you to get an idea of how fast stream processing with PHP can be
-// and also to play around with differnt types of input and output streams.
-//
-// This example accepts a number of parameters to control the timeout (-t 1),
-// the input file (-i /dev/zero) and the output file (-o /dev/null).
-//
-// $ php examples/91-benchmark-throughput.php
