Mladjan Gadzic commented on HDDS-9232:
--------------------------------------
Thanks [~szetszwo] for the suggestion. I had a chance to run it only once for
FSO bucket. Writing for 100k keys took around 4.5 mins according to freon
client (write time is about 1.5 min). I will run a few more tests to confirm
that this helps.
{quote}When setting it to 0ms, you should see a similar log message as below.

I could not see log mentioned above. However, I can see properties are set in
STARTUP_MSG. I'll get back to you with more info.
Logs from freon:

> Write performance degradation
> -----------------------------
>
> 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
> Labels: ozone-performance
>
> 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
> write performance.
