I don't know the code well enough, but I could imagine the following:

What would happen to the CPU usage if you had replaced the [bng]
objects with [bang] objects?  Or is the architecture such that an
object only computes if its outlet is connected to something?  If
that's the case, I could imagine that another difference between
[bang] and [bng] might be that the [bng] always has to compute the
bang whether or not its outlet is connected -- maybe it would have
more to do with this than just its being graphical.  But really I
don't know, just speculating late at night.
