The best way to go about your problem is to have a look at the Code Efficiency Page, for which I am attaching the documentation below:
Each parameter you set will affect your code depending on the model you are using.
If you are using Embedded Coder, you optimize the code in a generic fasion by setting the "Optimization Level" parameter to be "maximum". This would imply that the optimization is to be made keeping code generation parameters in mind. You could also go through the parameters specifically and understand if they will have an effect on your model or not. Do note that you will be disabling debugging by doing so. Attaching the documentation of "Optimization Level" parameter to give you a better understanding:
Hope this helps!
