Hi Andrew,

OK, let's focus on the areas where we have a higher difference and come back to this one.

This case is same test case with bug 1269690. let's dig more in #1269690 and come back this.

Cynthia, is this bug a duplicate of bug 1269690? These bugs report a performance problem on the same Google Doc test on the same hardware. The only difference is the Firefox and Chrome versions.

Hi Chris,

  This bug is only for tracking and recording the latest nightly build (at that time) result on the same gDoc test.

  So you are right about the difference, the only difference is the browser version.

  If you have concern about this I can set the status as duplicated.

[Chris Peterson [:cpeterson]]

Thanks. Since the only difference between these bugs is the browser versions, let's close this bug as a duplicate. I will change Tracking Flags of bug 1269690 to indicate that we can also reproduce the problem with Firefox 50 (Nightly).
