FYI, this is expected as OMTC introduces an extra copy of 2D canvases (which is what this benchmark is using). There are ways to fix that, but we are busy with higher priority items so this probably won't be optimised in the short term.

Testing on Windows 7, I get the same result on Chrome 59, IE 11, Firefox 54 and Nightly. I think this isn't relevant anymore (if it ever was).
