Yes.  Takes seconds.

I'm not sure I parse that very long sentence.  If by that, you meant
that scons just displays its cache, instead of reconfigureing everything,
then yes.  It takes seconds even on a RasPi.

You can turn that off with "scons -q".

We were talking about elapsed time, not text output volume.  If you
don't want to look at it, then just don't look at it.
