Actual results: The browser window stutters immensely. Expected results: There shouldn't be chopping scrolling.
Per request from Robert O'Callahan, this bug has been created as a clone of Bug 865546. While Bug 865546's fix helps performance, it still has some issues. Need to profile and attach results.
I'm actually having trouble profiling for any build 2013-01-18 and after. I had someone else on my team confirm the same thing. When I "Stop" the profiling, the profiling data shows up briefly and then almost immediately disappears. I am going to attach a video of this happening.
Did you install the latest profiler XPI from here? https://github.com/bgirard/Gecko-Profiler-Addon/raw/master/geckoprofiler.xpi

Performance seems to have gotten a lot better between 2013-05-09-03-10-47-mozilla-central and 2013-05-10-04-16-06-mozilla-central. https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ea059733677c&tochange=08be63954b6b
And in latest Nightly it seems to be even better yet.
Okay great. I will give it a try and report back. Haven't gotten a chance to do profiling on my side but will be pushing things around in my schedule to do that today. I'll also take a look at the latest nightly and see how that performs. Thanks!
While the performance isn't 100% of what it was before, we've also implemented some enhancements that negate the performance loss. Because of this, I'm comfortable marking this one as resolved and will reopen a new issue if the performance issues resurface. Thanks!
