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 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
