I know that Python is integrated _very_ closly to the Zope core, but to use a Python module you'll have to create an External Method and a file in the Extensions folder; and this might be slower than using DTML. Right? Basically, how much faster is DTML to Python (assuming the codes outputs the same thing)? The reason I ask is that I (probably as everybody else) want an as fast site as possible, but still use the power of Python. And also, whats the performance difference of using External python modules compared to the Python Method product?
