Re: The penalty for realtime imbecilitis
""The claim was QOS and 600+Mbps in a cheap consumer router"
No, it was that Firewall + NAT was not realistic on consumer grade hardware. I have shown that you are wrong on that.
I then added some specifics - that are also correct - in fact I under specified what the hardware can achieve. And yes that's with QoS enabled.
How effective the QoS is - is an entirely different question and is unrelated to your original claim - which didn't mention QoS...
