What is this, and why does it lead to hydronium/hydroxide ions moving through water much faster than other kinds of ions?

Autoprotolysis is simply when a proton (H+ ion) is transferred between two identical molecules. One of them will be bronsted acid (giving H+) and one of them will be bronsted base (gaining H+). So for water, an H+ ion is being transferred from one water molecule, thus forming a hydronium ion (H3O+) and a hydroxide ion (OH-).
