I use Plasma 5 everyday, and it is nowhere as fast as Xfce. And this is telling for Xfce, because Plasma 5 is pretty fast (once started). I'd say Plasma 5 is pretty fast. Xfce is instant. Xfce 4 is kind of timeless. I could use Xfce 4.14 today, and then go back in time to 2005 and use Xfce 4.2 on my Pentium 2 (333 Mhz) laptop with 96 MiB of RAM and it would still feel very familiar and look quite the same. Actually, this is the opposite for me: current versions of Xfce still feel familiar to me. No such thing can be said of KDE and Gnome. Even of Gnome 2 between the different versions.
