My cursor speed was too slow, but I already had the speed maxed out in System Preferences.
Thankfully you can use
defaults command line tool to increase the mouse speed beyond what you can do in the UI.
# read your current mouse speed defaults read -g com.apple.mouse.scaling # Set it to > 3, requires a restart to take effect defaults write -g com.apple.mouse.scaling 9
There are plenty more things you can change with this tool, do
man defaults to learn more.
