Again, in order to use these APIs, you must have the 'lock pages in memory' privilege set. This is why for 64bit systems, you don't need to set the 'awe enabled' option to 1 (it is actually ignored on 64bit systems).Perhaps we're having a semantic argument. There are a number of articles around that explain how 64-bit memory management works with the AWE Enabled option set. In fact, if you've turned on 'lock pages in memory' I believe you'll find that the AWE Enabled box is checked whether you like it or not; however, if you don't have "lock pages in memory" set then you can't set the AWE enabled switch. The overriding point is that AWE functionality is used on 64-bit machines. It isn't just a 32-bit feature. The difference is that the functionality provides a different set of benefits in a 64-bit environment.
I was not aware of that, point taken. I agree the question was lacking. I think what people should take away from this is that you want to get the memory settings on 64 bit correct; set Min/Max memory, and lock pages in memory. If the working set gets trimmed, performance is in the toilet.
