By default, the mouse movement scale factor is 1x.

defaults write NSGlobalDomain com.apple.mouse.scaling -float "1"

This setting is listed in the Mouse preference pane as the "Tracking speed" slider. Its ticks give the following values:

• 0.0 (which surprisingly, does not mean "no movement")
• 0.125
• 0.5
• 0.6875
• 0.875
• 1.0
• 1.5
• 2.0
• 2.5
• 3.0

This command allows you set a scale factor greater than 3x.
