Despite this, the performance of the rmap patch — especially on high-end systems and under heavy loads — is significantly better than the 2.4 kernel's VM system.
尽管如此，rmap的性能——尤其是处于高负载的高端系统——相对于2.4内核的虚拟内存系统还是有了显著的提高。
Since this wait queue is used sparsely, a smaller wait queue implementation using hash queues to find the correct wait queue has been implemented in the rmap patch.
因为这个等待队列极少用到，所以在rmap补丁中实现了一个更小的队列，通过哈希队列来找到正确的等待队列。
