I get about 2000 IOPs with this test:
# rados bench -p volumes 10 write -t 8 -b 16K hints = 1 Maintaining 8 concurrent writes of 16384 bytes to objects of size 16384 for up to 10 seconds or 0 objects Object prefix: benchmark_data_fstosinfra-5_3652583 sec Cur ops started finished avg MB/s cur MB/s last lat(s)
I read quite some time ago here that it is possible to do some local caching for an rbd. I think this would increase the iops considerably. But you have to search for this can't really remember how it is called / done.
