For the ptr_ring I was considering bumping the refcount of pages
allocated from outside the 1G pool, so that they do not get recycled.
I deferred optimizing that until I can get some production results.
The extra CPU cost of loss of recycling could outweigh the IOTLB win.
All very exciting stuff, I wish the days were slightly longer :)
Know the problem of (human) cycles in a day.
Rizzo's article describes a lot of experiments, that might save us/you
some time.
Speaking of saving time - if anyone has patches to convert mlx4 to page
pool I'd greatly appreciate!
