In jewel, as you mentioned, there will be "--max-objects" and "--object-size" options.
That hint will go away or mitigate /w those options. Collect?

The io hint isn't sent by rados bench, just rbd. So even with those
options, rados bench still doesn't have the io hint, rbd caching,
object map, or cloning, which all make it a bit different from what rbd
does.

Are those options available in:

# ceph -v
ceph version 10.0.2 (86764eaebe1eda943c59d7d784b893ec8b0c6ff9)??

No, they were just recently merged are aren't in any releases yet.
