a couple benchmarks to compare python and c++ runtimes. a detailed analysis and presentation of the results can be found in the in the main directory. i will include some graphs produced below for a quick glance a the results. the tl;dr version of the results is that python is about 50x slower when doing compututions. the pyqt graphics library, however, is only about 5x slower than the standard c++ version of qt.
check out the notebook if you are interested. it explains everything.
