In my experience people make too many changes all over the map and lose track what has been changed or not and whether it makes any difference. It is best to change something and try it long enough to know whether it makes any difference or fixes the problem. If not change it back and do this with everything until you know for sure it was the solution. I don’t have an answer that will magically solve the problem and i also don’t know everything. I work with what i have and what i research using trial and error methods and solutions to known problems. I can only say that this is a low power dual core processor with 4 threads. It can be easily overwhelmed with processes whether on Windows or Linux.
Edit: I know that’s probably not what you want to hear but it is part of the equation.
schedutil should be good, “performance” might just force the CPU to permanently stay at the highest possible frequency, even if no work is being done. Schedutil is a smart mode, should be only marginally slower (say 1% or 2%) than “performance” but with the added benefit of smartly turning the frequency and power draw down when not needed.
As I said I don’t think this is a problem with the CPU, based on the screenshots and results you posted. Spikes in CPU usage when you open a new tab is perfectly normal (when taking into account your particular CPU). if your usage doesn’t go up to 100% and stay there that means the CPU is not the limiting factor. But it was a factor that needed to be excluded, before testing other things.
I’d be looking at any acceleration settings in the browser itself, or switch to another browser and see if you experience the same issues (Firefox is a good candidate as Kresimir said earlier). If you experience the same issues with Firefox, you can at least rule out the browser itself as a problem.
I will try other browsers but at the moment Firefox seems to slow down too
@ricklinux No i have a good connection. 80 mb / s in download
The slowness is not in the navigation, but in the “animations”, for example when I close and open a tab
The profile in Ram did not completely solve the problem, but I have read what it is and will keep it anyway, because it looks good to me. Thank you for your suggestion.
@Dev0ut Not yet. I’ll try it.
I’ve seen it’s in the official repos, so I can try it out. Unfortunately the kernels installed by Aur for my pc would be unmanageable, it would take hours to compile.
I would be interested in seeing your RAM usage during these slow downs? Also what is your swappiness set at, it might be aggressively swapping? Do you have a swap partition or swapfile? Lastly mounting your cache in /tmpfs is basically like having no cache at all. Sure it will access it quickly if you have visited the site recently i.e. during this boot. The second you turn your laptop off, that cache is gone, hence no stored images.
Hi, ram usage during slowdown hardly exceeds 5gb, so it’s not saturated
About the swap, the system slows down with or without swap enabled
When swap is enabled, it is enabled with this parameter:
/etc/sysctl.d/99-swappiness.conf
vm.swappiness = 10
Possibly even with
vm.vfs_cache_pressure=50
I could try to use the browser for a while with the physical cache and not in ram, although I don’t think that’s the problem
Interesting, I was convinced this is a laptop, given the laptop specific CPU. I assume this is an AIO or compact desktop machine?
One final question from me, are you using an SSD or HDD ?
One more thing, I don’t expect switching kernels to have any effect whatsoever on the perceived performance. I wouldn’t even add that try to the possible solutions list.
+1. Of the big 3 KDE is the lightest choice these days. Although it or xfce are very close…
I definitely felt like Windows is faster than anything Debian based I’ve used recently, but Arch based feels the same to me. Although i generally use Firefox, i can’t comment on chrome… I wish I knew what to add to this, other than it’s very surprising and quite the opposite of what I normally notice.
