If you click on the line, you can see the actual C code that Cython generated for you. Doing that, you'll notice that there are quite a few more python calls stemming from yellow lines than the white lines. The more yellow a line is, the slower it will probably run because it is doing more python stuff than just straight C stuff. Some python stuff is unavoidable, though, like the def statement above. Note that the coloring of the lines is heuristic; it's not a guarantee that those lines are the ones that are running slowly. But it does help quite a bit if you want to speed up your code: make sure that the inner loops don't have very much yellow in them. Personally, I think the coloring of the lines and the ability to click on them is one of the neatest features about developing cython in the notebook.
