I have already gave it a try. Degradation is visible. It took 26min and 13sec
to write 100k keys.

> Key: HDDS-9232
> URL: https://issues.apache.org/jira/browse/HDDS-9232
> Project: Apache Ozone
> Issue Type: Bug
> Affects Versions: 1.3.0
> Reporter: Mladjan Gadzic
> Priority: Blocker
>
> It is observed on real cluster using unsecure Ozone HA (3 OMs, 3 SCMs, 3DNs)
> that write performance degraded significantly after Ratis upgrade to 2.5.1
> (https://issues.apache.org/jira/browse/HDDS-8382). At the time of writing
> this ticket, it takes master branch ~25mins for 100k keys to be written,
> while it took 1.3.0 release ~2mins for the same number of keys.
> Test was done using single freon client on OM node. Command
> {code:java}
> ozone freon rk --bufferSize 4096 --factor THREE --keySize 10240
> --numOfVolumes 1 --numOfBuckets 1 --numOfKeys 100000 --numOfThreads 10
> --replication-type RATIS {code}
> was used for that purpose.
> Commit before HDDS-8382, HDDS-8550 (sha
> 290e5f2ba1826a2084c1745e458872dc76c7ae91) did not exhibit degradation in
