1.4% regression in jetstream at 387897:387924

Project Member Reported by toyoshim@chromium.org, Apr 25 2016

Issue description

Reference graph might show a similar regression, but it's very small compared to the Score test. Reference graph could just show a noise, but test graph does not look like.

Hum... result wasn't reported automatically.

Here is a copy and paste from the report page.

chromium@387905,v8@a0d2f240c3187.6 0.547723 5 good
chromium@387905,v8@139617b0d5185.4 0.547723 5 bad

Assign to mstarzinger@ who landed 139617b0d5185, but we may need another v8 bisect to find more accurate revision?

CC: prasadv@ as a today's bot sheriff to triage the issue that result wasn't reported, also could help to run another v8 bisect?
IIUC, then there are 24 CLs in the regression range mentioned in comment #4.

Looking at the results from a wider time range, this appears likely to have been noise.
