> indexes (also known as logical files or access paths) with a larger

> optimizer and allows the database paging to be more efficient on a query.
> For example, one customer after applying the PTF's saw a 40% decrease in

> The larger page size only be used on indexes created over SQL tables and
> SQL-created indexes. The 64K logical page size will be used automatically
> for any index that is created over an SQL-created table - this includes
> both
> SQL-created indexes and indexes created for constraints.
