Duong commented on HDDS-9665:
-----------------------------
I just tried both commands in a test cluster and they resulted in quite similar
performance.
{code:java}
[root@rhelnn01 ~]# ozone freon ockg -s 10240000 -n 10000 -t 10 -b pe-ofs -v
vol1 --prefix="ofs-100GB"
-- Timers ----------------------------------------------------------------------

Is there anything specific, like the number of existing keys in the test
bucket, or the ozone version I can give it another try.
