WebIf this happens, most performance gains are of course lost and even if it does not, there is a tiny overhead in calling such a method from Cython compared to calling a C method. Parameters of either type of function can be declared to have C data types, using normal C declaration syntax. For example, Pure Python Cython WebSep 3, 2013 · To compare speed I compiled your get_r and get_r_profile functions in plain C. The plain C get_r_profile appeared to be 2.5-3 faster than the Cython one so maybe it's an option to compile get_r separately and link to it from Cython? Interestingly, depending on the optimization flags the compiler seems to skip the call to get_r altogether! Dunno how …
