How to optimize simulation time in Simulink

I am working on my simulation model in Simulink, where I am using "NN Predictive controller" module. I am trying to display the output of the NN Controller in Scope 2.

As you can see in the picture I have 2 signals from workspace. Both are discrete signals (sampling frequency 360 Hz) - both are vectors of 3600 rows.

In NN Predictive controller I have trained neural network to signals of the same size and set the sampling interval to 0.1.

When I run this simulation it runs approximately for 10 hours. Is there any way to minimize the simulation time without increasing the sampling interval in NN Controller? My second question: Why it takes so long?

If you need additional inforation about this model please let me know.

Thank you

Use Accelerator Mode or Rapid Accelerator Mode in SL. You can switch the mode in the drop-down list where currently normal is selected.

In the Accelerator Mode part of the Modell is compiled. In the Rapid Accelerator Mode additionally all scopes are deactivated. For data evaluation you than need to store to the workspace and/or file and analyse it later.

See: http://de.mathworks.com/help/simulink/ug/how-the-acceleration-modes-work.html
