Peformance

I am exporing some different language options.
I know there were some tests done back in the day when when pyogre was getting started, But what sort of performance are you getting out of python/pyogre compared to C++.

Python is obviously slower then C++, but that is not the point. Python is design for fast prototyping, write basically everything in Python, then create optimized parts, only the parts that need to be optimized, in C/C++. You can program orders of magnitude faster in Python, and saving programming time can be infinitally better then saving a few cycles in code that is not run that often.
