warp delete result : Skipping DELETE too few samples

[morningcafe]

minio RELEASE.2024-05-27T19-17-46Z warp 0.10.0 I have cluster of 6 node x 8-ssd and use this command but it not working:

warp delete  --host=lab-minio{1...6}:9000 --access-key=minioadmin --secret-key=xxxx --obj.size 1MB
>>>
----------------------------------------
Operation: DELETE. Concurrency: 0
Skipping DELETE too few samples. Longer benchmark run required for reliable results.
---------------------------------------

I tried some diffence option:

• prepare put 200k object on warp put and use --list-existing on delete (for used existing current object),
• use diffrence object size,
• more --concurrent
• or increse --duration, The result alway like above. Please help
