[MPlayer-users] does debug compile affect performance?

OTOH, larger binary results in a larger cache footprint.
And larger cache footprint might lead to slowdowns.
But all that depends on CPU type and memory bandwidth.

I've heard that it might be worth optimizing for size with -Os for 
some processors that have a small cache and slow memory combination.
But these processors are probably not useful for mplayer / mencoder...
