Benchmark comparison between -mm+NoOOM tree and with the new zones

I know you had also previously posted a very simplified version of your real fragmentation avoidance patches. I was curious if you could repost those with the other benchmarks for a 3 way comparison. The simplified version got rid of a lot of the complexity people were complaining about and in my mind still seems like preferable direction.

Zone based approaches are runtime inflexible and require boot time tuning by the sysadmin. There are lots of workloads that "reasonable" defaults for a zone based approach would cause the system to regress terribly.
