About remote memory references - yes it's supposed to be slower in
NUMA (but 7-8 times looks like a rather huge penalty for doing this?).
But anyway - see my latest post where I simply referenced dual over
and over and over. It's a read-only memory location so hardware should
be able to cache it to avoid remote memory references?

...reading from dual cannot be described as "a read-only memory
location." There is a lot more to it than that.
