matlab - How to optimize simulation time in Simulink -

i working on simulation model in simulink, using "nn predictive controller" module. trying display output of nn controller in scope 2.

as can see in picture have 2 signals workspace. both discrete signals (sampling frequency 360 hz) - both vectors of 3600 rows.

in nn predictive controller have trained neural network signals of same size , set sampling interval 0.1.

when run simulation runs approximately 10 hours. there way minimize simulation time without increasing sampling interval in nn controller? second question: why takes long?

if need additional inforation model please let me know.

thank you

picture:

use accelerator mode or rapid accelerator mode in sl. can switch mode in drop-down list normal selected.

in accelerator mode part of modell compiled. in rapid accelerator mode additionally scopes deactivated. data evaluation need store workspace and/or file , analyse later.
