Just reporting my setup here for any of the PFSense/OPNSense folks.
Running PFSense on an old Lenovo M920s SFF desktop with an Intel X540 NIC, Intel i8700 CPU and 16GB RAM.
Full line speeds (8Gbps) with no jitter at load (PFBlocker enabled), 4-6Gbps with Suricata running, 1-2Gbps using OpenVPN client.
Using about 23W on average.
