Four years old. IP 0.1 vs CP 2.3. Sheesh.

Close to 3 years old but somewhat more meaningful ...

"""IronPython 0.7 is up to 1.8x faster than Python-2.4 on the standard
pystone benchmark. The key to IronPython's performance is that it
compiles Python code to .NET Intermediary Language which is then
translated to optimized machine code by the runtime."""

Where did you get "a few times faster" from?
