Is the second run of the same query also slow?

This test is related to the previous test, and it checks whether the slowdown is caused by some of the necessary data not fitting into the memory or being pushed out of the memory by other queries.

If the second run of the query is fast, then you probably lack enough memory. Again, see Chapter 10, Performance and Concurrency, for details about this.
