Hello Mel,
You helped some time ago with contention in lock_pages on very large boxes.
You worked with Jack Steiner on this. Currently I am tasked with improving this
area even more. So I am fishing for any more ideas that would be productive or
worth trying.
I have some numbers from a 512 machine.
