Would it be possible to get a copy of the sbperftest capx?
I ask because I would like to compare performance/stability across crosswalk versions, namely 7, 8, 9, and 10. This is related to the infamous janking issue, on which we finally seem to be getting some traction. I'm trying to test a theory that this originated with Chromium v38, and that the regression spanned multiple platforms.
If, for whatever reason, you would prefer to keep that test internal, I understand. I can mock up something on my own, but this would sure save time.

I'm not sure it would be useful. As far as my own investigation has shown, the measurements the test produces do not correlate with dropped frames due to v-sync. (E.g. the measurements can say everything's fine while it's janking to hell, or the measurements can be showing loads of jank when it's running perfectly smoothly.)
A better way to test that would probably just be to make a large smoothly scrolling background and visually inspect it on different platforms.
