Description wendy.wang 2015-03-09 08:52:32 UTC

There is a bug: 
Bug 87438 - [IVB/BDW Bisected] Firefox-fishbowl.trace and Firefox-fishtank.trace performance reduced ~96%
https://bugs.freedesktop.org/show_bug.cgi?id=87438

Based on Bill Spitzak's comment, 87438 bug need actual fix though " require adding code to pixman so that the filtering can be done in the X server. Otherwise making images into pixmaps in an attempt to speed things up actually make it slower as they just have to be read back into the client program to do the transform.
"

So filed this bug to actually fix Cairo performance regression issue and set 87438 as will not fix.
