Metric	Description
Array Wastage	The gap (by a percentage) between the average number of rows per fetch that the array can hold, as defined in the arraysize parameter of the various fetch operations of the specified SQL query, and the number of rows actually retrieved. For example: if the average setting of the arraysize parameter was 5, and the average number of rows actually retrieved per operation was 10, the value indicated will be 50. Ideally, the value of this parameter is 0; any other value indicates the need for additional sql.net roundtrips per each SQL query execution.
