Is it really that slow? The ode_solver class, for instance, allows you to define the RHS as a cython function, and behind the scenes a pointer to the RHS is then passed around as it were any other compiled function. I don't think this would be too much slower than a generic C implementation. I haven't done any speed tests, but I always find the ode_solver class to be very fast.
