Dear all, I recently changed my physical pfsense by virtualizing it on Proxmox, after that using 3 Gigabit network interfaces when I do a speed test on the links the speed does not exceed 100 Mbps. However, in the PFSense web interface, the cards appear with speeds of 10Gbps if there is something to be done because this way I cannot use the full speed of the links I have.
[SOLVED] Low PFSense Proxmox network performance

You should get full rate in pfSense assuming you have the resources to handle it, which I'm guessing you do.
Some obvious questions:
1. Has your host NIC negotiated at > 100Mbps?
2. Did you follow the Netgate guide and disable hardware checksums? [https://docs.netgate.com/pfsense/en...ble-hardware-checksums-with-proxmox-ve-virtio]
3. What resources have you allocated to pfSense? What's CPU use during saturation?

Ok, all looks sensible there.
Without knowing what host CPU, I'd say that's pretty high CPU use (3 CPUs though - what! where is your OCD?) if you're only pushing through 100Mbps; I think I'm struggling to top 20% over 2 vCPU (from an i7-7700) with a 500Mbps downlink.
What about LAN-side NIC? Can you transfer a file to/from pfSense from inside the network and see how that performs?
