cs.chromium.org is very slow lately

Project Member Reported by cbiesin...@chromium.org, Jun 14 2016

Issue description

Version: Version 53.0.2763.0 dev-m
OS: Windows 7

What steps will reproduce the problem?
(1) Load https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/layout/LayoutGrid.cpp?type=cs&q=SubtreeLayoutScope+grid&sq=package:chromium&l=1
(2) Try scrolling

What is the expected output?
Scrolling and interactions are very slow

What do you see instead?
It should be fast, like it used to be

Please use labels and text to provide additional information.

 
I can confirm it's very slow while the page is loading on 53.0.2763.0 dev, but a lot faster on 51.0.2704.84.

Any idea when this started happening? What platform(s) are you seeing this on?
I have only tested on Windows 7 -- I noticed it this week, but I don't know exactly when it started unfortunately :(

Would be great to do a bisect to try to track down when this started. I'll see if I can repro it on windows when I get back to my desk.

Fail to reproduce on either win 7 or 10 on 52 or 53. Do you have any extensions installed perhaps?
Hm, I feel like this is much better in 53.0.2781.0 canary (64-bit) which has szager's change above. There is still a 1-2 second hang while the page is loading though.

I have only the default Google extensions in this profile.
