Hello,
I am working with a Simulink model that contains several MATLAB Function blocks and a 6-DOF block. The runtime for the model is relatively high (approximately 3-5 minutes in real time per second of simulation time) and I would like to optimize the model to improve this.
The main function that is being called includes a sub-function that creates a local structure (with nested fields) and returns it as an output to the top-level function; I believe that this may be the main driver of the slow runtime, but any other advice would be appreciated.

Use Simulink Profiler to determine which part of the model is consuming the most execution time: https://www.mathworks.com/help/simulink/slref/simulinkprofiler.html?searchHighlight=simulink%20profiler&s_tid=srchtitle_support_results_1_simulink%20profiler
Adjusting solver settings can often improve performance. The Solver Profiler can help with this: https://www.mathworks.com/help/simulink/slref/solverprofiler.html
Accelerator and Rapid Accelerator modes can also help.
Thanks.
Mark.
