Not much has changed performance wise, apps are still slow to startup e.g kate, RAM usage hasn't come down, and logging out remains problematic and & resource intense process, why can't this damn thing log out in reasonable time 1~2 sec? Massif'ing few apps reveals LOTS of heap memory leaks all over the place, simple apps such as kmix end up chugging 20MB once they stumble upon problematic libs such xine that is known for leaking memory very bad. Besides few visual glitches it runs pretty good in the end

. With git noueveau, git drm & KMS on, git xorg, git mesa, I get a full blown DE with RAM usage ~170MB (indexing disabled plus few other things) on x86_64. Once they patch the leaks they can easily get down to ~130MB just like GNOME.
