Browser and GPU process are much higher compared to Brave
- May 22, 2019
Edge Insiders,
My name is Tim Scudder and I’m a member of the Edge performance team. I wanted to provide an update on this issue: we were able to repro the problem locally, we have a fix coded, validated and are now working to get this change into our next dev drop (estimated to be 76.0.166.0).
We apologize for the inconvenience, but truly appreciate everyone’s help in isolating the problem.
NOTE: We are also aware of a https://bugs.chromium.org/p/chromium/issues/detail?id=962784 that also has CPU/battery impact that originated upstream in Chromium's codebase. This issue has been fixed upstream and we are also working to make sure the fix is in our next dev drop (again, estimated to be 76.0.166.0)
Regards,
Tim Scudder

I am putting together a testing/result log (using Windows Task Manager and all three computers) that I will submit to Microsoft Edge Support either later today or Wednesday, depending on when I get it done, and ask MES to open a bug on the issue.
I've found in the past that opening a bug through MES focuses attention on an issue. In the past, MES has asked me to resubmit to Feedback using the bug number as the title, and if that happens, I will come back to the thread and report that so that any of you who wish to can do the same.
While I think that the difference between Edge Chromium's Browser Task Manager and Windows Task Manager in measuring/reporting CPU usage is interesting, the important thing to remember is that we have identified a bug in Edge Chromium (CPU use at rest) that is not hardware dependent, not tab/website dependent, is both consistent and persistent, manifests at Edge Chromium's core, and does not manifest in Edge (Classic), Chrome or Firefox.
We need to get Microsoft focused on this, and keep them focused until it is resolved.
Stay focused! Yet bug fixing priority is again defined by the Program Manager and Roadmap schedule. Another way to try is contacting this forum Mods, they can push Edge Support to at least Reply to your bug report email. :)

I've had good luck with MES responsiveness when reporting other bugs. On earlier occasions, MES e-mailed me shortly after submission, I submitted the test/results log, MES replicated, and then opened the bug. The point of opening a bug (as I understand it) is that the process kicks the issue onto the roadmap schedule, usually with a higher priority than it might otherwise have had. I don't have access to the Program Manager or the Roadmap schedule, so I do what I can to kick the issue up the ladder.

I would expect the moderators to visit this thread today or tomorrow (that seems to be the pattern after a weekend thread breaks out) and report that they will notify the appropriate team(s).

Thank you for all your testing. This is absolutely a bug. I have found a reproducible pattern, too, regarding GPU usage.
With this tab open & focused + YouTube's homepage on Edge C, I click between Edge C and my desktop to change focus.
When Edge C is focused
Total: 4% CPU + 1% GPU
Edge C: 2% CPU + 1% GPU
Desktop Windows Manager: 2% CPU + 0% GPU
When Edge C is not focused:
Total: 12% CPU + 30% GPU
Edge C: 6% CPU + 15% GPU
Desktop Windows Manager: 6% GPU + 15% GPU
Somehow, if Edge C is running in the background (without focus, then!), it absolutely snacks on your CPU and GPU.

This system has an i5-8600K and a NVIDIA GT 710. So, even "high-end" CPUs are noticeably affected.
