    In April, I wondered why a simple COUNT(1) query took 30 seconds.  Now I know it could be a lot worse:

    [bobbojones@test (none)] > SELECT COUNT(1) FROM r2;
    +----------+
    | COUNT(1) |
    +----------+
    |        0 |
    +----------+
    1 row in set (59.76 sec)

    It just took nearly a minute to determine that the table is empty.

    That’ll do, MySQL.  That’ll do.
