Instead, focus on understanding what the workloads exercise to help us determine how to best use them to aid our performance assessment. As database performance is heavily influenced by the performance of storage, network, memory, and processors, we must understand the upper limit of these key components.

Whether the page is dirty or not (a dirty page has changes on it that haven’t yet been written back to durable storage). Index_A has 200,000 pages at its leaf level, and Index_B has 1 million pages at its leaf level, so a complete scan of Index_B requires processing five times more pages. The table has 1 million rows. ) ; GO.

The engine processes the row through parent operators before releasing the shared lock prior to locking and reading the next row. When the engine chooses page-level locking granularity, it takes and holds a shared page lock while processing rows on the current page and then releases the lock right before acquiring a lock on the next page.
