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.

Ilia has been working on an optimizer which needs to be tested, and cleaned up, and analyzed before it can be part of APC. There is quite a bit of work to do here, including porting to PHP 5.3 (and HEAD). There are also other possible optimizations to be done. After working on this, you'll have a very good understanding of PHP's internals. |

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.

+ | Written by Derick Rethans, XDebug is the most powerful tool to help every developers and debuggers in the debugging and profiling of their algorithms, applications, | ||
+ | |||
+ | XDebug can generate profiler output files that are easy to load with KCacheGrind and WinCacheGrind. However, many people do not have that installed, and all the OSX people have no tool to run the profiled file (Unless they install KDE on X and then install KCacheGrind). | ||
