    Unanswered: Repeating query not running faster

    Running DB2 101 fp2 on Red Hat Linux.

    We have a query that repeats several times consecutively. The issue is that the subsequent execution times are not running faster than the first execution. I would think that the explain plan, once in the sql cache, would enable quicker times on subsequent executions.

    Is there anything I can do to help subsequent executions run quicker?

    Thanks in advance.

    subsequent executions could only benefit from bufferpool
    depending on size of result set / available memory / bp size settings
    time to prepare a statement can be ignored
