Hello list, is there any calculation of expected I/O available?
I've a test system running 6 hosts 4 OSDs each using SSD - i get 20.000 to 40.000 IOP/s not as much as i expected but OK right now. If i replace the SSDs on one host with spinning disks but still using dedicated journal on ssd (20GB / Disk/OSDK), i'm not able to get more than 300 to 400 iop/s this seems to be pretty low. Everything tested using 0.56.4 and Qemu RBD.
