 Make a tool to convert Zend bytecode into [[http://llvm.org|LLVM]] bitcode. In a first phase this could replace the Zend dispatcher/executor and in a 2nd phase it could perform some simple operations inline (while still relying on the Zend engine for non-trivial opcodes). Make a tool to convert Zend bytecode into [[http://llvm.org|LLVM]] bitcode.

 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.

 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).  XDebug can generate profiler output files that are easy to load with KCacheGrind and WinCacheGrind.
