[ceph-users] RBD + ZFS + NFS = bad performance. How to speed up?

Hello. I'm using rbd disks for zfs and on the zfs I use NFS. I see 10-50MB/s top. When I use the rbd disk in the VM environment it can reach 1GB/s RW so there is nothing wrong with the rbd and the cluster. Also I'm sure about ZFS+NFS performance when zfs on the real device. But when they work together I can't get even %10 performance. I think something is wrong, it shouldn't be that bad. Ceph version: Nautilus 14.2.16 RBD Data = EC Pool RBD Metadata = SSD replicated zpool create $testpool rbd0 exportfs /testpool Is there anyone who has tried it before?
