Browser and GPU process are much higher compared to Brave
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 VSync timer tick issue 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
Are you stating that Edge Chromium uses only ONE core of ANY CPU? Where did you get it from? Also, I don't need to look at any Task Manager - when my laptop fans are sounding like turbines all the time I know Edge is idling, now uninstalled. :)
My main concern is, Edge Preview devs have an approved roadmap, which directs them to concentrate on full set feature transfer, and moving from Chrome to MS services. Which means, performance optimization issues may be very last ones on their mind right now. So no such bugs might be fixed in forceable future, thus cutting off current enthusiastic but fast shrinking testers pull. There always be some hardcore folks, knowing little about tech, but asking to add this or that classic button or check box thinking Edge team "forget" it, so targeted "web noise level" will be maintained.
sambul95 I stated nothing of the sort. I just stated that what the "CPU %" shown in Task Manager means is different between the two... task managers. To compare the two you have to multiply or divide by the number of logical cores in your system. If one process within Edge process uses more than one CPU core it will register higher than 100% in Edge task manager
Aaron44126 Thanks, Aaron. I was able to replicate your results on a Dell XPS 8920 (i7, 4 physical cores, 8 logical processors). The Edge Chromium Task Manager showed 139.6% CPU use, while at the same moment, Windows Task Manager was showing 20.5% CPU use. I think you've confirmed that the two measure/report CPU usage on differently, and your single/multi core explanation makes sense to me.
It well may be that one CPU core power in https://superuser.com/questions/162590/setting-permanent-process-cpu-core-affinities-in-windows or Chrome https://chromium.googlesource.com/chromium/src/+/master/docs/threading_and_tasks.md is enough per Chromium process to render most webpages. It looks like Browser Task Manager is designed to reflect that as you suggested earlier. :)
sambul95 I ran the SunSpider JavaScript benchmark and here you can see an Edge process using more than 100% CPU. (At one point it spiked to over 200% but I missed grabbing a screen shot for that.)
Following the same logic, can you give some alternative links for Chromium Task Manager? I'm merely asking for sources, not sure how it measures the load. :)
It's pretty common knowledge that the CPU usage percent in Windows Task Manager is normalized across the CPU's logical cores. A quick search would have told you. :)
For example:

https://superuser.com/questions/994191/what-does-cpu-column-means-on-process-tab-on-task-manager
I'm sorry to repeat my basic question: where did you get this info from? :) Can you support it by any web links or screenshots?
