I'm getting bad performance with YouTube page loading. (not playback issue)
For example,
- Go to https://www.youtube.com/user/MissSmiles4u/videos
- Open DevTools->Network, check 'Disable cache' on
- Reload several times
Average of DOMContentLoaded and load
66.0.5 -> 2.11s, 3.81s (51 requests, 8.14 MB / 2.36 MB transferred)
68.0a1 -> 7.93s, 8.13s (54 requests, 7.22 MB / 2.20 MB transferred)
Here is profile data on 68.0a1.

Here is data on 66.0.5 for comparison.

hi, i think those may be the same observations that are already discussed in bug 1546313. do you get the same regression range as well?

No, I couldn't get regression range since there is no significant gap...
Umm...
The issue seems to be gone now.
Average of DOMContentLoaded and load
66.0.5 -> 4.19s, 4.38s (54 requests, 7.22 MB / 2.20 MB transferred)
68.0a1 -> 4.02s, 4.19s (54 requests, 7.22 MB / 2.20 MB transferred) (build id 20190511220902)
I'll close this report as invalid or worksforme later.
This issue is reproducible on build 20190510214931 but not on build 20190512093034. (tested both now)
Something bugfix must have resolved this issue.
