Description of problem: Running multiple DD test against RBD images in my test environment. 3 VMs with 1 core each, 2GB RAM each, 2 OSDs each. The DD shows me between 200 and 300 ops per second and around 300KB/s each against 5 RBD images. All the test environment runs on an Apple i7 Macbook Pro with 16GB RAM.


Version-Release number of selected component (if applicable): 2.0 (0.0.39)


How reproducible:
100%

Steps to Reproduce:
1. Create multiple RBD images of 128MB
2. Map each RBD image on a node
3. On each node run a dd if=/dev/zero of=/dev/rbdx bs=1 count=131072000 &

Actual results:
Although the value of ops per second may be accurate, the bandwidth is probably showing the correct number but with the wrong unit. 1,358,280.2 KB/s hence 1.3 GB/s

Expected results:
Probably 1,358,280 B/s
