just I feel... Considering i686 which divides memory into NORMAL and HIGHMEM, it seems that 4G to 8G servers looks stable under various workload in my experience.
Then, at least, 12.5% to 25% of "Total Memory - Hugepages" memory should be under ZONE_NORMAL. But this is from experience of 32bit/SMP :(
Thanks, -Kame
