PAGEIOLATCH_UP

Description

This wait type accumulates while SQL Server is waiting for a page to be retrieved from disk and loaded into memory. The page will be retrieved in update mode (for modify and versioning operations). If this value is high it is likely that disk or memory are not keeping up with the workload
