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 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 can confirm the same behaviour. Much, much higher CPU & RAM usage than on previous builds.

 

I wrote a longer response here.

 

This is on both an i5-8600K / 16GB / 250GB SSD desktop and an i5-6200U / 8GB / 500GB SSD laptop. This resource-hogging is new to Edge C; the previous Edge C build was fantastic.

 

My CPU fans have not quieted once with Edge C 76.0.159.0. There is absolutely a week-by-week regression for the Dev channel (and others are reporting the same on Canary builds, too, having started earlier and the bug survived into Dev).

 

Let us know what troubleshooting information you need, Microsoft. I recommend everyone willing to post here also send a Smiley report from within Edge, so Microsoft can collect diagnostic data.
