Auto hide delay tweaking
Enter this into Terminal to make the Dock show without a delay :
`defaults write com.apple.dock autohide-delay -float 0; killall Dock;`

Maybe you want to have a long delay (5 seconds) so that you never accidentally trigger the Dock:
defaults write com.apple.dock autohide-delay -float 5; killall Dock;

To restore defaults:
defaults delete com.apple.dock autohide-delay; killall Dock;

Animation speed tweaking
Enter this into Terminal to make the Dock show without animations :
defaults write com.apple.dock autohide-time-modifier -float 0; killall Dock;

It's still nice to have a short animation (0.2 seconds) and this line makes it possible:
defaults write com.apple.dock autohide-time-modifier -float 0.2; killall Dock;

To restore defaults:
defaults delete com.apple.dock autohide-time-modifier; killall Dock;
