Well this is likely the result of the SLUB regression. If you allocate an order 1 page then the zone locks need to be taken. SLAB queues the a couple of higher order pages and can so serve a couple of requests without going into the page allocator whereas SLUB has to go directly to the page allocator for allocate and free. I guess that needs fixing in the page allocator. Or do I need to add a mechanism to buffer higher order page allcoations to SLUB? - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
