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 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
