Sure, i tested the performance of this way, there is the result: The origin way: 2m56.561 2m50.651 2m51.220 2m52.199 2m48.066 The way of using accessed bit: 2m51.194 2m55.980 2m50.755 2m47.396 2m46.807 The way of ignoring accessed bit: 2m45.547 2m44.551 2m55.840 2m56.333 2m45.534 I think the result is not bad. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
