Debian Xfce vs Gnome - Linux Hint
https://linuxhint.com/debian_xfce_vs_gnomeThe difference is smaller than in the previous example but Xfce retains performance superiority. Finally an example which broke the trend, I opened Steam on GNOME: It shows 4.1% used by the CPU, 4.0% by the system and 1.043 MB RAM while below Xfce shows 12.2% of CPU used by the user, 2.9 the system and 859 MB ram.
