 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.

 +**Note from Travis Swicegood:**  Why rewrite run-tests.php when it's already been done with the PHPT project.  See http://phpt.info for the project's Trac.  It still has room for improvement.  Parallel test processing is on the list for two major releases out (see http://phpt.info/ticket/12 for stubbed out info on how to do that in PHP), but if someone wants to implement it before then I'd be happy to help.  Multiple output support is already built-in, but new Reporters could definitely be added as could micro-benchmark support. 
  
 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.
