Is rados_write_op_* any more efficient than issuing the commands individually?

[Dan Jakubiec <dan.jakubiec@xxxxxxxxx>]

Hello, I need to issue the following commands on millions of objects:

rados_write_full(oid1, ...)

rados_setxattr(oid1, "attr1", ...)

rados_setxattr(oid1, "attr2", ...)

Would it make it any faster if I combined all 3 of these into a single rados_write_op and issued them "together" as a single call?  

My current application doesn't really care much about the atomicity, but maximizing our write throughput is quite important.

Does rados_write_op save any roundtrips to the OSD or have any other efficiency gains?

Thanks,
