This wait type accumulates while SQL Server is waiting for a page to be retrieved from disk and loaded into memory. The page collected will be used for destruction (delete operation). If this value is high it is likely that disk or available memory are not keeping up with the workload

Suggested solutions

  1. Add additional memory
  2. Investigate disk latency
  3. Increase the maximum memory allocation
  4. If large delete operations are emptying an entire table consider using TRUNCATE TABLE
  5. Indexing, look for high disk I/O queries
  6. Enable data page compression if CPU usage is not suffering
