Proxmox backup speed

[mazzo66]

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

Update with iperf3

proxmox -- nas 90 Mbits/sec
nas --proxmox 900 Mbits/sec

why theese difference ?

broken cable ? wrong routing? broken switch ?

 

[mazzo66]

i will try it

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 ?
