Thanks for the figures. More generally, I think 3.4.x is overall faster than 3.3.x because someone really competent (Jan Hubicka) sat down a few weeks before the release and produced a series of patches only aimed at cutting down the memory consumption and speeding up the compiler. So that's definitely doable, albeit certainly hard. -- Eric Botcazou
