----------------------------
下面是改进后，使用 ReadPoint 与 Fast 的合并性能测试，Fast 的耗时为1195秒，而 ReadPoint 的耗时为1322秒。

> Original Estimate: 48h
> Remaining Estimate: 48h

> In the scenario where all seq pages overlap with unseq pages (for example,
> the sequence point is 2 4 8, and the unsequence point is 1 3 5 7, etc), with
> four sub-threads, Fast performance is slower than ReadPoint.
