> After merging this commit, the write speed in atoms testing declined.
>
> We inferred that this change lead to compaction grabs more CPU/IO resources,
> which decrease available resources of write/read.
>
> After we change the parameter `iops_per_min` from 50 to 30, the scenario
> still exists.
> See this snapshot,

> Let's investigate the details.
