Hi, > As many of you know we made huge improvements in PHP 5.4 memory usage > (enabling higher concurrency) and runtime performance.
Here are the unit test results for https://github.com/xp-framework/xp-framework and https://github.com/xp-framework/xp-language after applying workarounds for two bugs in current SVN (see https://gist.github.com/1746945).
