Hugepages are strictly an harder-to-use optimization for specific people who love to tweak (e.g. database administrators or benchmarkers). From what I heard so far these people like to have more control, not less. -Andi -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
