Hi Casey,
Thanks for your reply.
Just to make sure I understand correctly- would that only be if the
S3 object size for the put/get is multiples of your rgw_max_chunk_size?
whenever the object size is larger than a single chunk
Kind regards,
Tom

Hi Thomas,
I see that you're familiar with rgw_max_chunk_size, which is the most
object data that radosgw will write in a single osd request. Each
PutObj
and GetObj request will issue multiple osd requests in parallel,
up to
these configured window sizes. Raising these values can potentially
improve throughput at the cost of increased memory usage.
