Other Interpreters You Might See... Unladen Swallow Blazing fast, uses llvm and in turn may compile! x86/x86_64 only really Sponsored by Google http://code.google.com/p/unladen-swallow/ Jython Python written in Java and running on the JVM http://www.jython.org/ performance is about what you expect IronPython Python running under .NET http://www.codeplex.com/IronPython PyPy Python in... Python No where near ready for prime time http://codespeak.net/pypy/dist/pypy/doc/
CPython Interpreter Notes Compilation affects interpreter speed Distros aim for compatibility and as few irritations as possible, not performance compile your own or have your systems admin do it same note goes for most modules Regardless of compilation, you'll have the same bytecode and the same number of instructions Bytecode is portable, binaries are not Linking against shared libraries kills portability Not all modules are available on all platforms Most are not OS specific, 90% are available everywhere x86/x86_64 is still better supported than most
