Comment 2 Daniel Vetter 2014-05-15 14:11:09 UTC 
Needinfo to answer whether the slowdown is a regression. If so please bisect.
Comment 3 Chris Wilson 2014-05-16 11:33:16 UTC 
Might as well wait until bug 78724 is fixed.
Comment 4 Daniel Vetter 2014-05-16 22:05:41 UTC 
Let's hope this is now resolved, too. Please reopen if it's not the case.
