Comment by Sam Kleinman (Inactive) [ 10/Sep/12 ]

When running a query using the explain() functionality, this will
cause the query engine to re-calculate the query plan. This, in turn,
can cause some queries to run slower. If you're timing queries, you
shouldn't use explain(); if you're explain()ing queries you shouldn't
trust the timing.
