I too am experiencing this issue in Australia with an NBN HFC connection. I have a commercial firewall which i get > 900mbps but down to under 300 with opnsense.I have tried the MSS setting which slows it down slightly.
Its a real shame as it makes the solution unusable for me, if anyone has an ideas I'm open otherwise I guess its ipfire for me.
Cheers
