Keep buffer pool

The defragmenter USES the buffer pool for this movement in order to keep the data in sync with other USES.

在移动时，碎片整理程序会采用缓存池来保持与其他使用的同步。

If the buffer pool is large enough to keep the required data in memory, less disk activity will occur.

如果缓冲池大到足以在内存中保存所需数据，就会发生较少磁盘活动。

Keep in mind that adjusting this value is often a short term solution, particularly if you request additional buffer pool space, which requires more overall memory.

请记住，调整这个值常常只是短期解决方案，尤其是在请求更多缓冲区池空间时。
