Statement usage summary

Contains a summary of how many statements are executed and the number of times they are executed during the performance monitor collection period. This information provides the user with a high level indication of how often the same SQL statements are used multiple times. If the same SQL statement is used more than once, it may be cached and subsequent uses of the same statement are less expensive. It is more important to tune an SQL statement that is executed many times than an SQL statement that is only run once.
