Large I/O detail

This section provides summary information for each pool individually. It contains a block of information for each 4K, 8K, or 16K pool configured in cache. It prints the pages brought in (“Pages Cached”) and pages referenced (“Pages Used”) for each I/O size that is configured.

For example, if a query performs a 16K I/O and reads a single data page, the “Pages Cached” value is 8, and “Pages Used” value is 1.
