I have a bad exmaple - updainting to Fedora-16 installs an Audacious
version which was ported to GTK3.
This gtk3 based version definitivly scrolls slower than its
predecessor, it can't even keep up with scrolling the song-list - a
basic gtk3 table.

Unfourtunatly oprofile and sysprof don't seem to find the installed
debug-symbols, after I get more insight I'll file a bug. (which most
likely won't be even looked it, at least thats what the general
attitude seems to be regarding to performance bugs & regressions).
