Relative speedup vs PHP, lower is better, normalized to Zend PHP 5.5.0
HippyVM is an implementation of the PHP language using PyPy technology. It started off as a research project by Maciej Fijałkowski for Facebook, and was later expanded. As of now, it contains a reasonably fast and complete implementation of core the PHP language, including implementation of many PHP's builtin modules (though not all, yet). At present it does not include a reasonable web server integration, so it's not usable for use in production in the current form.
HippyVM is being developed by Baroque Software, experts in the area of virtual machines.
