Faster Simulink if scopes are switched off?

My questions concerns a Simulink model that is still being refined. The model contains >20 scopes to make it easy to spot troublesome behavior. When I perform many runs of the model from a script, the scopes are not useful. Should I put them behind a switch (iDebug=1) so that they only execute when the model implementation is being checked? Will 'turning off' the scopes reduce the simulation time?

Will 'turning off' the scopes reduce the simulation time?

Yes.

Thanks. What about turning off 10 'To Workspace' blocks that are only useful when checking the model? Will that also reduce simulation time?

[Sean de Wolski]

yup.
