Howdy folks, I'm running some tests on OPNSense 19.7.9_1-amd64  vs PFSense 2.4.4-RELEASE-p3 (amd64)  - both of them are running as virtual machines on the same host with no tuning but all patches applied. All I'm doing is installing iperf3 and running it in server mode for the tests, here are the results:

OPNsense:

The virtual machines are running under proxmoxve (linux/kvm) with same hardware settings (see screenhots). Needless to say I can get full gigabit performance through pfsense but about 4x lower using pfsense - is this expected?

Big thanks for a great product and great community
