PHP has some algorithms that aren't asymptotically optimal. E.g. some string handling functions are O(nk), although they could be implemented in O(n). Analysis of the current situation and implementation of better algorithms (along with many tests) are the job. | PHP has some algorithms that aren't asymptotically optimal.

The run-tests.php script that is used to run PHP's suite of PHPT tests has grown over the years and needs to be refactored. Two areas of improvement include leveraging multi-core systems to run tests in parallel and support for micro-benchmarks in addition to tests. | The run-tests.php script that is used to run PHP's suite of PHPT tests has grown over the years and needs to be refactored.
