    copied!<p>What are your opinions and expectations on <a href="http://code.google.com/p/unladen-swallow/wiki/ProjectPlan" rel="nofollow noreferrer">Google's Unladen Swallow</a>? From their project plan:</p> <blockquote> <p>We want to make Python faster, but we also want to make it easy for large, well-established applications to switch to Unladen Swallow.</p> <ol> <li>Produce a version of Python at least 5x faster than CPython.</li> <li>Python application performance should be stable.</li> <li>Maintain source-level compatibility with CPython applications.</li> <li>Maintain source-level compatibility with CPython extension modules.</li> <li>We do not want to maintain a Python implementation forever; we view our work as a branch, not a fork. </li> </ol> </blockquote> <p>And even sweeter:</p> <blockquote> <p>In addition, we intend to remove the GIL and fix the state of multithreading in Python. We believe this is possible through the implementation of a more sophisticated GC</p> </blockquote> <p>It almost looks too good to be true, like the best of PyPy and Stackless combined. </p> <p>More info:</p> <ul> <li>Jesse Noller: <a href="http://jessenoller.com/2009/03/26/pycon-unladen-swallow/" rel="nofollow noreferrer">"Pycon: Unladen-Swallow"</a></li> <li>ArsTechnica: <a href="http://arstechnica.com/open-source/news/2009/03/google-launches-project-to-boost-python-performance-by-5x.ars" rel="nofollow noreferrer">"Google searches for holy grail of Python performance"</a></li> </ul> <p>Update: as DNS pointed out, there was related question: <a href="https://stackoverflow.com/questions/695370/what-is-llvm-and-how-is-replacing-python-vm-with-llvm-increasing-speeds-5x">What is LLVM and How is replacing Python VM with LLVM increasing speeds 5x?</a></p>
