See for example: <https://arewefastyet.com/#machine=35&view=single&suite=speedometer-misc&subtest=Angular2-TypeScript-TodoMVC-CompletingAllItems-sync>

This can be seen across the board.

The regression ranges from AWFY are inconclusive, as each graph shows a different one...

Backed out bug 1341569 at smaug's request. Not sure how long it will take AWFY to pick up the change, but I pushed the backout to inbound so it'd get picked up as soon as possible.

Thanks, the backout seems to have been effective!

For example, https://arewefastyet.com/#machine=36&view=single&suite=speedometer-misc&subtest=Angular2-TypeScript-TodoMVC-CompletingAllItems-sync went back to normal.
Thanks for investigating this everyone!
