I am not sure if poor performance is strictly a bug, but the performance is very poor when an inline SVG references (animated) parts of another SVG through a "use" element. Since duplicating the animations by hand in two 'unlinked' SVG images has great performance in comparison, I cannot see why the browser could not optimise the "use" element better.
