Public bug reported: Any operation that probes stuff over XRANDR is really slow. Running just "xrandr" takes slightly less than 4 seconds. A bit of experimentation reveals that adding:
Section "Monitor" Identifier "HDMI1" Option "Ignore" "True" EndSection ...to xorg.conf fixes it. I have no HDMI ports at all, so this is not a problem. Only HDMI1 seems to be the problem.
