    I have low backup speed on nfs server. max 100Mbit/sec

    if i run iperf...

    nas as server, proxmox as client, 95 Mbits/sec
    proxmox as server, nas as client 943 Mbits/sec
    nas as server virtual machine as client 843 Mbits/sec
    proxmox as server, virtual machine as client 5,5 Gbits/sec
    virtual machine as server, proxmox as client 5,5 Gbits/sec

    Why nas as server and proxmox as client is slow ??


    Proxmox Virtual Environment 5.0-30

    my pc as server proxmox as client

    cable, routing, switch uhm.......

    another test iperf3

    nas as server vm in proxmox as client
    [ ID] Interval Transfer Bandwidth Retr
    [ 4] 0.00-10.00 sec 1.01 GBytes 866 Mbits/sec 0 sender
    [ 4] 0.00-10.00 sec 1.01 GBytes 866 Mbits/sec receive

    vm in proxmox goes well.
    the hardware is the same.
    may be some configuration in proxmox software ?
