I checked the patch from comment 15 against 3.1.1. While xrandr is faster switching my screen it still takes a long time (3.8 seconds) to read out the current information. What is worse during switching or asking the information X is blocking! meaning not even the mouse is moving. This also happens when other applications ask for display information (e.g. wine seems to do that a lot).
