About the Fedora Gnome vs EndeuvourOS KDE... the issue here isn't Gnome. It's actually Fedora.<p>In my testing on a similar hardware (also Core M3 and 4gb RAM), Arch-based distros was the best with low RAM. And I tried like, probably 50 distros since last year...<p>Gnome on my HW with Arch, is as fast as KDE, and use less memory than KDE (in theory, I know RAM is a complicated subject).<p>Why fedora is problematic on low end hardware? Because well, Fedora uses packagekit, which is a ram hog, and this is pretty known. Is not the only reason though, I believe there's some other defaults that make it slower than arch on my HW, like zswap vs zram.<p>In my experience with weak CPU and low ram, was that zswap was actually the best choice. On such low RAM like 4gb, you'll really need a swap, you can't run from this. And zram won't be enough, in my experience.<p>Which I guess is one of the reasons why Arch go very well here, as is one of the few distros right now that does a nice default for zswap.<p>With Fedora, and most other distros, I get constant freezes when the RAM is full (which is pretty easy to do with 4gb), and this never happen on arch based distros.
