[ceph-users] Re: Mapped rbd is very slow

rbd -p kube bench kube/bench --io-type write --io-threads 1 --io-total 10G --io-pattern rand elapsed: 14 ops: 262144 ops/sec: 17818.16 bytes/sec: 72983201.32

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. -- With best regards, Vitaliy Filippov
