Of course. It has almost no effect at all, as far as I can say. These are also important:

  defaults write com.apple.dock autohide-time-modifier -float 0.1
  defaults write -g NSUseAnimatedFocusRing -bool NO
  defaults write com.apple.dock springboard-show-duration -float 0
  defaults write com.apple.dock springboard-hide-duration -float 0
  defaults write com.apple.dock springboard-page-duration -float 0.1

Then it takes just as much time, but instead of movement you get smooth fading between views :)
