Proxmox Support Maximum network speed (10Gbps ?)

[Damonz]

Hi All

I have a machine have 100Gbps network card , and I install the proxmox on the machine .When I provision a VM with VirtIO (paravirtualized) network interface ,found I can only get around 20~30 Gbit/sec network speed. Is there any way I can improve my network speed to 100Gbps ?

Hello Damonz,

It is possible you are hitting the limit of your memory speed, you can take a look at network queues (multiqueue) in [1], you might also look into PCI pass-through [2].
