How to improve the speed of S-Fcn or else tell me some other function which will run at each sample time.

Im having a simulink model and I want to update its output value to guide panel at each sample time. So for that I tried "S-Function" and inbuilt matlab syntax "add_exec_event_listener". But both are reducing my simulation speed in huge amount.

I have 130 outputs from model. Without S-Fcn model is running 22 samples/sec. But if I add S-Fcn it is less than a sample/sec.

So please provide me some ideas to improve the speed or else tell me some other function which will run at each sample time.
