Unfortunately, I don't have performance numbers from inbound to confirm yet, since we didn't land yet. The most recent try run with the patch in bug 860493 applied can be found here: https://tbpl.mozilla.org/?tree=Try&rev=b33b98df38de Datazilla (perf-o-matic?) somehow doesn't like to display performance numbers for me on try. Maybe more experienced minds can make this work?
