If I want to use librados API for performance testing, are there any

Ok, I really think I have patched tcmalloc wrongly.
I have repatched it, reinstalled it, and now I'm getting 195k iops with a
single osd (10fio rbd jobs 4k randread).
So better than jemalloc.

Hi,
also another big difference,
I can reach now 180k iops with a single jemalloc osd (data in buffer) vs 50k
iops max with tcmalloc.
I'll retest tcmalloc, because I was prety sure to have patched it correctly.

OK, good to hear.

When we end I/O struct request with error, we need to pass
obj_request->length as @nr_bytes so that the entire obj_request worth
of bytes is completed. Otherwise block layer ends up confused and we
trip on
rbd_assert(more ^ (which == img_request->obj_request_count));
in rbd_img_obj_callback(
