toejam316: The question is what are you trying to achieve with gigabit+ speeds? 

 

At the moment, I'm just trying to match the speeds I had last week with my previous provider. That was a 1Gb connection. I now have a 2Gb hyperfibre connection with Quic. I would expect, at the very least, I should be able to achieve similar speeds with the same hardware (excepting PPPoE). Even with PPPoE I would not expect my upload speed to be 300Mbps given the CPU usage is less than 5%.

 

You're not alone studdart.

With my previous fibre provider, I was able to consistently get over 900 down and 400 up.
That was a DHCP connection.

Since switching to Quic and PPPoE I now only get at most 800 down and 320 up.

I have a UDM SE which has a 2.5GB RJ45 WAN port.

Setting MTU to 1500 didn't make a difference in my testing.
The CPU usage on the UDM SE never goes above 15-17%

I was going to move to 2GB Hyperfibre with Quic but if I can't even get gigabit speeds there may be no point.
I'm not too worried about the small drop in speed as we haven't noticed any real difference in day-to-day use.

Latency has improved and our monthly cost has dropped. :)
