Question
Large pages are available in Windows Server 2003
and Windows Vista
.
But how do I enable large pages for my application?
Solution
Martin's answer is correct on Windows Server 2003:
You will have to assign the "Lock pages in memory" privilege to any user that runs your > application. This includes administrators
- Select Control Panel -> Administrative Tools -> Local Security Policy
- Select Local Policies -> User Rights Assignment
- Double click "Lock pages in memory", add users and/or groups
- Reboot the machine
On Windows Vista you need also make sure that the application is run as Administrator (by right-clicking on the application or the shell and choosing "Run as adminstrator".
In addition, it helps to have a freshly booted machine since the large pages can "run out" due to fragmentation of the heap.
