Why did you reference that last issue? I haven't had that CPU usage issue since Quantum was released.
- nh2 7y ago> Why did you reference that last issue? Because it's still happening, also on Quantum. I still see the 5-15% CPU usage on idle. If you strace Firefox, you'll see the syscall spam, even when the browser is apparently fully idle. This consumes a lot of battery power because it prevents the CPU going to sleep, even when you're looking at a still screen in Firefox (compare to gnome-terminal as mentioned in the bug report, which stops spamming as soon as nothing moves). My laptop lasts only half as long on battery when Firefox is on and showing a still screen.
- csdreamer7 7y agoI can confirm the strace messages and FF's 15% erratic usage on a dual core i3 Skylake laptop. I guess I never noticed it compared to how FF used to chug after long use and Google Chrome's same usage of around 30-40% of my cores.
