Disable Animated Window Zooming
Mac OS X Lion animates the opening of windows, making some things feel less than crisp, and really slowing things down in total when many windows are opened at once.
You can disable this behavior in Mac OS X Terminal:
defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool NO
defaults write NSGlobalDomain NSAutomaticWindowAnimationsEnabled -bool YES
