Discrete Derivative only in certain time steps

Im simulating a system with a discrete derivative block. Since its a very large system it takes very long to run. Is there ay possibility to change the time step of the derivative block, so that the derivation is only done like every 5 time steps or maybe every second. Or maybe there is a block to suspend the branch with the derivative block for a certain amount of time steps, so the simulation doesnt last so long.
P.S.: Im sure that the discrete derivation is the cause for the long running time. The system doesnt work with the casual derivative block btw.

Hi,
Step size and number of iterations affect the accuracy of the simulation. Choose a step size for the Simulink solver which suits your model.
