how can i measure the time taken by a certain block in Matlab Simulink

Hi guys, My Matlab Simulink is too slow. So, to solve this problem, I need to know which part is taken a long time during the execution time. I think the highlight block in the Figure below is the problem. How can I measure its execution time?

thank you in advance

It looks to me like you have an algebraic loop that Simulink has to resolve by doing numeric integration using an ode solver. That can happen any time you have feedback in the circuit. You might be able to adjust the solver parameters.

thank you for your answer, but I tried to do it before without any benefit.
