Testing and Performance

Testing

$ phpunit

Performance test

Sample application includes performance test. It can be run with default parameters

$ php sample.php -t

or with execution time measurement and specified number of iterations

$ php time sample.php -t=10000

If your system has debug assertions enabled it is recommended to turn them off. Just to give you an idea that debug assert are not free here is the execution time comparison

Debug asserts mode	Command	Execution time
Enabled	$ php -d assert.active=1 sample.php -t=10000	7.589s
Disabled	$ php -d assert.active=0 sample.php -t=10000	2.884s

The following command could be used for performance profiling with blackfire.io

$ blackfire --slot <slot number here> --samples 1 run php -d assert.active=0 sample.php -t=100
