I'm trying to stay away from rbd & qemu issues and just test rados bench on a non-virtualized client. I have a test instance newer drives, CPUs, and Ceph code, I'll see what that looks like. Maged's comments were quite useful as far as iops per thread. It seems like Ceph still hasn't adjusted to SSD performance. This kind of feels like MongoDB before the Wired Tiger engine... slow performance but with all the system resources close to idle due to threads being blocked.
