Slow bridge on proxmox
-
I have a new installation of PVE on a HPE dl380 g10. I set up fresh installs of 2 virtual machines - an ubuntu server 22.04 and a pfsense 2.7CE. I set up an linux bridge in pve and gave it an ip and added it to the Vms. When I run iperf from the ubuntu VM to proxmox I get a speed of ~22GB/s, about what I would expect from single thread performance of the host.
The problem is when I run iperf from pfsense to the host bridge IP ( or anything I connect to the bridge) I get a slow speed ~4GB/sec.
I have disabled hardware offloading per the pfsense guide.
Is this a known issue with the BSD virtio driver? Any Ideas what I can try to improve this speed?
Thanks

Only 4GB/sec... Don't run a firewall-appliance I guess.
