Only 350mbps speed using virtio network

[openasapce]

Helloooo

I run opnsense inside proxmox using virtio network card
and i can reach only 350mbps in download , the same vps with virtio, outside the opnsense reach 940mbps.

Where is the problem?
I was planning to use it on a 10gbps server, but E100 driver is only 1gbps speed and if opensense have problems with virtio driver, this is a big problem for 10gbps networks

Hi,

hard to guess, I'd start with playing around with the settings at -> Interfaces -> Settings
starting with toggle: Hardware TSO


And keep an eye on interrupt/CPU utilisation during network activity
e.g.
sudo top -PSH
