Sandra and Large Memory Pages

Warning W5010 : Cannot use large page memory pages due to lack of privileges.

Fix: Use the Local Security Policy to give yourself lock memory pages privilege.

Large memory pages greatly improve performance when large memory blocks are allocated.

User rights assignments are not registry keys, but there is a utility in the Windows 2003 Resource kit that can set Windows privileges, including Lock Pages in memory, and it works on Windows 7 too. The resource kit is a collection of tools available at:

You only need the program called ntrights.exe, which I'll attach to this post.

Example of turning on the privilege you need (my windows userid is "nick")

C:\Users\nick>ntrights -u nick +r SeLockMemoryPrivilege
Granting SeLockMemoryPrivilege to nick ... successful

If you ever want to turn it off:

C:\Users\nick>ntrights -u nick -r SeLockMemoryPrivilege
Revoking SeLockMemoryPrivilege from nick ... successful

These commands were carried out with UAC off, so you may need that or an elevated command prompt.
