System slow even after a restart, but not after a shutdown/power on

As the title says, does anyone know how to prevent this?

May be helpful if you run this command after a restart, to let us know which service is causing the slowness:

systemd-analyze blame

It’s also a good idea provide your system information:

Thanks for the reply. I’ll do that next time I feel my system slow.

But is there a way to do a “full reboot” when hitting the reboot button?

You can try REISUB instead hitting the reset button if your computer is hung:

I’m sorry, I expressed myself badly.

When I said reboot, I was saying clicking on the system restart button (on the menu).

Really surprising… :thinking:

Hope you can try the systemd-analyze blame command to see what’s going on.
