Nevertheless, your advice was IMHO sound even if the run-time speed is
considered.

The only reason why `clrscr' might not be the fastest version ever is
that it clears by lines, to only clear the current text window (which
might be part of the display).  Other than that, it already uses fast
assembly code.
