#
#   speed4-join1: Join three tables using IPK index.
#   speed4-join2: Join three tables using an index.
#   speed4-join3: Join two tables without an index.
#
#   speed4-view1:  Querying a view.
#   speed4-table1: Same queries as in speed4-view1, but run directly against
#                  the tables for comparison purposes.
#
#   speed4-subselect1: A SELECT statement that uses many sub-queries..
#
#   speed4-trigger1: An INSERT statement that fires a trigger.
#   speed4-trigger2: An UPDATE statement that fires a trigger.
#   speed4-trigger3: A DELETE statement that fires a trigger.
#   speed4-notrigger1: Same operation as trigger1, but without the trigger.
