Mac OS X: Reduce/increase workspace switching delay

Does dragging windows to the adjacent workspace in Mac OS X feel sluggish? Try lowering the according delay, e.g. to 0.1 seconds. For a persistent change, enter the following in a terminal:

defaults write workspaces-edge-delay -float 0.1; killall Dock

If you’d like to have a longer delay, try setting a value of 1.0 or even 2.0.
