Document performance comparison with nupic/ nupic.core #297

hi, I'd be interested in performance benchmark of the 3 implementations: java, py, c++? Specifically java against the two, as I'm aware of c++-py speeds.

I think a simple hotgym dataset (long version) with reasonable SP/TP settings would be all I'm asking for. I'll try to run the project in netbeans' profile mode.

OT: do you have any experience with interfacing python to java? As I have my other libs in python already..

Hi,

Can the C++ implementation be counted as a full implementation yet? To my knowledge there's the linux on vm / py, linux on vm / py-c++ hybrid, (not sure about windows), mac py, mac py-c++ hybrid?

Also, I haven't done any performance optimization / profiling to speak of htm.java (yet) so it isn't at full capacity - but - running the integration tests and unit tests side by side in Eclipse its easy to see that the Java version at least very much outperforms the Python version. (I'm not sure if what I'm seeing is the pure Python or the Python-C++ hybrid either).

I would like to see these comparisons as well... Again keep in mind that I'm sure htm.java can use a performance profiling effort.

Nope, I'm a Python noob... :-)

@breznak I assume when you referred to Netbeans that you were going to play around with this?
