YardStick

YardStick is a class, providing easy access to benchmarking.

It allows the embedded-in-code becnhmarks, such as:

…
$ys = new \Mudasobwa\Screwdrivers\YardStick(true);
$ys->milestone('YS1#Start');
$my_obj->perform_long_operation($param1, $param2);
$ys->milestone('YS2');
$my_obj->perform_long_operation($param3, $param4);
$ys->milestone('YS1#Finish');
$ys->report('YS.+'); // report measures for milestones `YS*`

The output will be looking like:

==== Results for tag: [1396189882.6664-YS1#Start]

Another way is to measure the specific methods (and/or compare them):

\Mudasobwa\Screwdrivers\YardStick::benchmark(
   new FlexibleString('Hello, world!'), 'replace', array('/l/', 'L')
);
