Hi!

I have similar problem. I upgraded (clean install) from Proxmox 3.1 to Proxmox 4.1
But instead doing backup to a usb drive, I use local disks.
After installing Proxmox 4.1 first few days backup speeds was as usual (05.01.2016. backup log):

I add NFS share and try to backup trough network, but problem remained.
Maybe someone can lead me in the right way?
