As you can see, the Deepin Desktop Environment is very feature-rich and awesome-looking. This might have you thinking that DDE will consume a lot of RAM or CPU. However, in reality, it’s relatively lightweight as it’s based on the qt framework.
Since we installed DDE on Fedora, which already ships with GNOME out of the box, we got the perfect platform for testing the performance difference between DDE vs. GNOME.
In our test, after a fresh boot into Fedora, we logged into GNOME and noted its htop score while idle. Here’s the result.

Then, to keep things fair, we rebooted our system again and logged in to DDE to note its htop score while idle. And this is its result.
Fedora GNOME
performance
So, as you can see, running Fedora with the GNOME desktop environment is taking up over 1GB of RAM. However, with the DDE, Fedora is just consuming around 850MB of RAM while idle. So, although DDE isn’t the lightest of desktop environments, it is certainly lighter than popular alternatives like GNOME.
