Can you test -rc3? Is that still ok? And are you perhaps using
Nouveau? There's a report of some graphics (?) regression since -rc3
about bad desktop performance:

https://bugzilla.kernel.org/show_bug.cgi?id=23912

but it doesn't have any more information yet (so if -rc3 _is_ good for
you, and you can add anything to that report, it would be good. The
original reporter is hopefully bisecting it now)
