Performance HORRIBLY degraded with many open tabs

I find myself waiting far too long far too often for UI control to return while Brave and/or Windows is off in the weeds doing god-knows-what. I watch the Brave Task Manager and the Windows Task Manager, looking for CPU-hog pages to kill.

  1. the refresh rate on the tasks monitor is too fast to conveniently ‘catch’ a process to kill on the first pass, making you wait with cursor over a line where the process was on a previous update. Cut the refresh rate and reduce the performance backlog. How about letting users pick the refresh rate?

  2. I’d like to have more information about the active tasks. Maybe an extension is slowing performance to a crawl? If I knew which extension was causing the resource waits, I could experiment with disabling it. “Dedicated Worker” is way too generic - give me the name of the extension or subsystem, so I can communicate effectively about it. “Extensions: Brave”, “Renderer”, and “Subframe: URL” are not helpful, especially when the task manager update resorts everything a half-second later.

  3. In general, I do NOT want windows that are not at the top of the UI stack using ANY CPU. Once painted, put that tab/window into energy conservation mode.

  4. With Brave updates coming out FREQUENTLY, ALL of the windows/tabs have to reload at every update, thereby making moot my considerable efforts to kill greedy tasks/tabs.

----- situational data points…
a) My usual hardware/OS:
Windows-11 on a 64-bit, 16-thread Intel Core i9-9980HK CPU @ 2.40GHz with 128GB RAM

b) I don’t know how many tabs I have ‘saved’ for subsequent review, but the scroll button in the Task Manager is about 22% of the length of the task list (if that helps).
