CONFIG_SLUB_DEBUG is not enabling debugging. It just includes the code to do so at kernel bootup. Not a performance problem. CONFIG_SLUB_DEBUG_ON is a performance issue since debugging will be on by default. CONFIG_SLAB_DEBUG is also a performance issue since this option makes slab run with debugging. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
