Hello all, I have a 3 node proxmox 3.1 cluster with freenas 9.1.1 storage backend. Hardware: Proxmox nodes: Xeon 1240v2, 32GB, 60GB SSD (supermicro hardware) Freenas node: Xeon 1220L, 32GB, usb stick freenas install, 16x3TB hdd (dataset 1 = 6 x 3TB in raidz2 + 1 Intel S3500 80GB for ZIL, dataset2 = 10 x 3TB in raidz2 + 1 Intel S3500 80GB for ZIL). Each proxmox node has approximately 5 vm's which reside on an NFS share on dataset 1 on the Freenas node. I have following problem: When making a backup of the vms the backup speed is max 10Mb/s which is very slow for the above hardware. The vms reside on an NFS share on dataset 1 and the backup NFS share is on dataset 2. To do some testing i have made a clone of a small vm to the local Proxmox SSD. When i make a backup of that vm the backup speed is very fast at ~250Mb/s. Seems like the NFS read speed is very poor. I have tried to mount the NFS shares as UDP instead of TCP, this did not change the slow read problem. Thank you in advance for your help.
