was (Author: JIRAUSER294158):
[~szetszwo] This is a test which uses the volume of vol1. The performance almost same as the volume s3v

> 0 size performance, about 8000 QPS, this represents the highest write performance of any OM.
> 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 indicate that the cluster itself has normal read/write performance.
