Same on Brave, 700% CPU usage before I closed the page.
Dumb question but those any percent over 100 mean?
I know 100% is full cpu usage, but what does 700% mean?
It means that your cpu has 7x more work to do than it is capable of executing. 100% is a full load of a single core, 700% will be 7 cores working at 100% each.
