KVM / Ceph performance problems

Hi,

I have an little performance problem with KVM and Ceph.

I'm using Proxmox 4.3-10/7230e60f, with KVM version
pve-qemu-kvm_2.7.0-8. Ceph is on version jewel 10.2.3 on both the
cluster as the client (ceph-common).

The systems are connected to the network via an 4x bonding with an total
of 4 Gb/s.

Within an guest,
- when I do an write to I get about 10 MB/s.
- Also when I try to do an write within the guest but then directly to
ceph I get the same speed.
- But when I mount an ceph object on the Proxmox host I get about 110MB/s

The guest is connected to interface vmbr160 → bond0.160 → bond0.

This bridge vmbr160 has an IP address with the same subnet as the ceph
cluster with an mtu 9000.

The KVM block device is an virtio device.

What can I do to solve this problem?

Kind regards,

Michiel Piscaer
