Browser and GPU process are much higher compared to Brave

Hi! I was comparing Edge vs Brave and I noticed that Edge uses about 30-50% of my CPU in Browser task manager (both browser and gpu) while Brave uses less than 10% combined. I think there is some p...

    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

Keep in mind: It appears that there is a discrepancy between the number reported between Windows Task Manager and the browser's Task Manager.  Windows Task Manager reports the CPU use where 100% would mean that all logical CPU cores are fully loaded.  (i.e. In a system with 8 logical cores, 100% would mean that all 8 are under a full load whereas a single-core load would be 12.5%.)  The browser task manager reports 100% for one core worth of full load, so an 8-core load would be 800%.  Something to keep in mind when making comparisons.

Thanks, Aaron.  I was wondering why the metrics were so different. Now I know.
