| CB math in Python in 10x slower than Julia | |
| Python est math time = 2651*1.93139100075e-06 = 0.00512011754298825 | |
| Julia est math time = 2651*2.801677289999e-7 = 0.00074272464957899 | |
| Therefore math time is not to blame for difference | |
| Therefore 12% penalty just from Python interface overhead (extracting solution, adding constraints) |
