Hello Christian,
Thank you for your detailed answer!
I have other pre-production environment with 4 Ceph servers, 4 SSD disks
per Ceph server (each Ceph OSD node on the separate SSD disk)
Probably I should move journals to other disks or it is not required in my
case?

Timur,
As far as I know, the latest master has a number of improvements for ssd
disks. If you check the mailing list discussion from a couple of weeks back,
you can see that the latest stable firefly is not that well

Hello all,
I installed OpenStack with Glance + Ceph OSD with replication factor 2 and
now I can see the write operations are extremly slow.
For example, I can see only 0.04 MB/s write speed when I run rados bench
with 512b blocks:
rados bench -p test 60 write --no-cleanup -t 1 -b 512
