In the thrill of the hunt, I overlooked one itsy bitsy detail.
This load still seems a tad artificial to me. What real world load
would run with 2/3's of the nodes having max'd out memory?
I'm suspecting that its worth some effort, to improve it, but not worth
major effort to get ideal performance.
I'm still open to more persuasion however.
