Kvm pfSense 100Mbps instead of gigabit

Did you disable Hardware Checksum Offloading?

@viragomann Yes, I tried with Hardware Checksum Offloading both enabled and disabled but it didn't make any difference.

@marius_herta
It has to be checked, when running on KVM. Save it and reboot the VM.

marius_herta

@viragomann I did that, I rebooted between enabling/disabling it, but the speed was still ~95Mbps regardless of whether it was enabled or disabled.

@marius_herta said in Kvm pfSense 100Mbps instead of gigabit:

I ran speedtest cli on the host and the test result was ~95Mbps
I replaced the modem with a Raspberry Pi 4B and the result of the iperf3 test between the Pi and the host was ~100Mbps

Did you run this tests on the host itself or on a VM behind pfSense.

Your LAN NIC is an USB device. Such devices can make much troubles. But that shouldn't be involved in above tests if you did it on the host.

marius_herta

@viragomann I did the tests on the host which connects to the internet through pfSense. I don't have other VMs besides the pfSense one.

@marius_herta
So I would run speedtest cli on the host bare metal to see I it's issue with pfSense.

@viragomann I followed your suggestion and this was the result:

No idea, what else should be wrong in pfSense.

On my installation I get full 1 Gb/s speed through pfSense running on KVM with virtIO NICs.

I still doubt that's an issue with your pfSense.

Well, since the test is with the host, and pfsense is not involved, why it is a pfsense issue.

(Unless you mean something else)
In any case I would steer clear of anything usb.
even if it works, its totaly unreliable on the long run, since unpluggin it, or moving port would "make" new interfaces..

The host connects to the internet through the pfSense VM.
