I noticed that even without decoration, fast focus switches drive my CPU usage up, much more so than in other non-tiling window managers. Running top gave me a surprising insight: it's not xmonad but the X server that consumes that many cpu cycles when focus switching.[...]
This matches my observations: http://thread.gmane.org/gmane.comp.lang.haskell.xmonad/12168
At this point, I'm simply pondering what can be done about it, as one of the reason's I'm using xmonad is that I want a lightweight desktop environment. (When fast focus changes drive one of my cores to 50%, that's hardly lightweight.)
