Also note 16 bytes of those 24 bytes, you need to spend them too if you remotely hope to perform as good as AutoNUMA (I can already tell you...), they've absolutely nothing to do with the background scanning that AutoNUMA does to avoid modifying the apps. The blame on autonuma you can give is 8 bytes per page only, so 0.07%, which I can probably reduce 0.03% if I screw the natural alignment of the list pointers and MAX_NUMNODES is < 32768 at build time, not sure if it's worth it. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
