DESCRIPTION

bencher is a simple script to run benchmark scenario with Benchmark (Benchmark.pm). It lacks bencher features like filtering participants/datasets/modules, listing participants/datasets or other actions. But it is small and does not have any non-core dependency.

EXIT CODES

0 on success.

99 on command-line options error.

OPTIONS

--count=i, -c

Specify count to pass to cmpthese().

==head2 --timethese

Use timethese() instead of cmpthese().

==head2 --cmpthese

Use cmpthese() (the default, so normally it is not necessary to use this option).

ENVIRONMENT

DEBUG => bool

Will print debug messages when set to true.
