title: Time complexity of scipy's integrate.solve_ivp
body: <p>I use scipy's integrate.solve_ivp function to solve an ODE over a time interval. The method and precision is fixed as 'rtol=1e-5, atol=1e-5, method=&quot;RK45&quot;'. But when I change the time interval from [0,1] to [0,0.01], the speed of solving is only twice faster. How can I configurate to make it 100 times faster?</p>
