I'm working with small corridors right now, but we are very judicious with our point names within our templates and once we identify the resultant breaklines as surface breaklines, the DTM is practically instantaneous and as we edit the corridor, the contours update immediately.
I can't speak for large data sets, but when working with roadway designer in earlier versions, I have had issues where others created many of the templates and had point names that were very inconsistent along the final corridor and that proved to be a nightmare.
I am a huge proponent of having a very strict naming convention and having it setup in the template library as a predefined point list with matching styles/templates. This encourages the use of fixed names and styles as appropriate and makes downstream efforts less complicated.
