Eric, I'm assuming the increase in tasks run is expected. There was also a small increase in CPU usage. From https://chromeperf.appspot.com/group_report?rev=447346, it doesn't look like there was a direct effect on frame_times or latency.

Any room for improvement? Or should we close as WontFix?

I think this is expected, I'll do some benchmarking this week to make sure.
