Hi Georg,
I am just curious: what is so slow ? (I did not look into the source ...)
I use also python for offline computation (not with pd yet) and it is quite fast - so is the interface to pd the problem ?
To my experience python is quite fast, when the underlying C components do most of the work (like with pyode, numpy, etc.). The C-python interpreter can't be called fast on the other hand, at least compared to C/C++. If you do DSP processing using Python statements (not numpy) it's really a waste of cpu.
greetings, Thomas
