Hello Ole,

what's about this MSDN post regarding 64-bit operating systems?

"How to: Enable the Lock Pages in Memory Option (Windows)"

SQL Server 2008 R2

The Windows policy Lock Pages in Memory option is disabled by default. This privilege must be enabled to configure Address Windowing Extensions (AWE). This policy determines which accounts can use a process to keep data in physical memory, preventing the system from paging the data to virtual memory on disk. On 32-bit operating systems, setting this privilege when not using AWE can significantly impair system performance. Locking pages in memory is not required on 64-bit operating systems.

Regards,
