rbd -p kube bench kube/bench --io-type write --io-threads 1 --io-total

It's a totally unreal number. Something is wrong with the test.
Test it with `fio` please:
fio -ioengine=rbd -name=test -bs=4k -iodepth=1 -rw=randwrite -runtime=60
-pool=kube -rbdname=bench
Reads are very very slow:
elapsed: 445 ops: 81216 ops/sec: 182.37 bytes/sec: 747006.15
elapsed: 14 ops: 14153 ops/sec: 957.57 bytes/sec: 3922192.15
This is closer to the reality.
