Comment 30 for bug 1872796

Seems the rendering performance penalty of desktop-icons-ng on my machine is roughly 10%. That's not terrible and especially considering desktop-icons-ng is implemented as a full-screen GtkWindow (not a Clutter widget) in a separate process(!)

If you need better performance then just remove the extension via the 'Extensions' app. I'm really not sure what can be done about compositing it any faster though. Maybe more local redraws instead of global redraws?
