Hey,
I love arch linux, but i have a problem i think.
When i look at the ressorces in taskmanager the cpu's are often over at 50% but at processes all that is shown is gnome-shell between 8-20% most of the time (maybe firefox 1%).
My CPU is Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz
in Windows 10 it was most of the time under 10%. Am i doing something wrong?
It's not lagging or anything but i would think my pc should run gnome better?
I dont have much stuff going on in the background except firefox and openvpn

are you using hyperthreading, and are they stepped down?
even so, they should be lower, but it's a starting point.
does top or htop show the same usage?

Im using hyperthreading. If i disable it, it makes no difference and i googled it, but i dont know how to stepp them down.
Top shows the same usage :

intel-ucode installed?

I just installed intel-ucode and followed the archlinux instructions on microcode. the output after a reboot is (dmesg | grep microcode):
[ 1.005607] microcode: sig=0x506e3, pf=0x2, revision=0x74

Also noticed: I can get the cpu to 50-60 % just by quickly scrolling up and down in firefox . Is that normal ?

Firefox should use the GPU (a.k.a. hardware acceleration) to compute the scrolling, so no. Seems like that isn't working.
Do you have a dedicated GPU as well?

You noticed that the top dumps shows a load of 12.875% ?
Random fancy load indicators that show random fancy numbers are random fancy rubbish.
Whether FF uses GL and whether that's HW accelerated depends on the actual system setup.
Wayland or Xorg? (does that btw. matter reg. the cpu load?)
In case of Xorg: run "glxinfo"
In firefox: "about:support", look at the graphics section.

You have wayland installed, or are you running it? If so, does the problem also happen in Xorg?

I really dont now. Maybe i just install arch from scratch again. I just typed what the guy on the video said, when I installed arch.

You should follow the ArchWiki rather than third party video or blog guides as they tend to be wrong more often than not. If you have trouble understanding the wiki you can always ask in here, but we can't help with setups following Youtube videos.
Also, blindly copying and pasting is never a good idea, even if it is from the ArchWiki or these forums. Understand commands before entering them and ask if you have trouble understanding them.

Please, please, please read (and understand) the installation guide
You will come out the other end knowing how your system is set up.

none of your cores, real or virtual, is at 50%, so there doesn't look like anything to worry about. even at 50% that isn't worrisome in itself. a core at 100% is beneficial if it's running a task to get it out of the way, that's why frequency scaling is more power efficient than older methods such as turning off cores
your cores will step themselves down if they're in dynamic mode, or stay stepped down in power-save mode. stepped down cores run at a lower frequency to save power

Log into gnome on xorg and compare behavior and values there.
FF says you're on software emulation GL - what mean's you're running it through Xwayland or on Xorg with broken driver installation. In any case your GPU won't do and CPU spiking is expectable.
And I sign the comments about how silly it is to
a) follow a video tutorial
b) blindly
If you want to stay with Arch, better break with that habit.

Okay; thanks for all the answers.
Just installed it again with the installation guide and im going slow. Didnt even set up a desktop enviroment yet.
Maybe i'll just stick with the console *jk* Its fun there
