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?
