I tested 1us, 5us and 10us. This is not a rigorous test, but can observe the
difference in performance.

> 0 size performance, about 8000 QPS, this represents the highest write

> the `hdds.ratis.raft.server.log.appender.wait-time.min` of om had been set to
> 0ms by default.

> This represents the performance limit of the DN, about 6000 QPS, which can
