Details
Displaylist send times (IpcProfileCounters::send_time also included with other stuff in the "DisplayListIPC" graph) are sometimes quite high (14ms isn't uncommon on youtube's front page for example.
It is the time between when the built display list is posted by the content process and when SetDisplayList is processed by the render backend (doesn't take into account the time to send it to the scene builder thread).
I suspect that part of these time spikes come from slow frame builds that make the render backend thread unavailable to pick up the SetDisplayList message.

Fixed by sending transactions directly to the scene builder (I don't have the bug number handy).
