 * Ops (operations) mode: order table activity by the number of operations MySQL performs on them.
 * I/O mode: show where MySQL is spending it's time in file I/O.
 * Locks mode: show order based on table locks
-* User mode: show ordering based on how long users are running queries, or the number of connections they have to MySQL.
