Well, I don't think I looked at RSS, but I can tell you for sure that
even multimedia programs or games that use all free cpu time run with no
slowdown at all when compiled with -g; I tested this several times.
Never checked mplayer, though, but results should be the same. But I
don't know how exactly MP_DEBUG and -DDEBUG will affect preformance,
there may be a reason in testing that...
