Very first world problem. UDM SE cannot get more than 1400Mbps down on 2GB connection from Aquiss. Martin did advise it was underpowered. I'm very much tied into the Unifi system for cameras, sensors, Wifi so did not ideally want to change and I'm sure I can live with this but realistically what are the options.
- Sell the UDM SE. Get a new router that can do decent pppoe speeds and have Network run on docker on my nas to control the ap's and buy the Unifi NVR for protect
- Run double NAT with a decent router in front of UDM SE
- Live with current setup...
Unless you have a genuine use case where you will saturate a 2Gbps line regularly, option 3...
I'd have thought it would be able to do higher, I'm sure I've seen users posting speed tests closer to 2.5 Gbps. There were also some EE users on Openreach testing at 1.6 Gbps.

Are any of you using PPPoE with your own router ?
Are there any benefits to doing this apart from removing the double nat

I was doing some monitoring via ssh and top and watching it hit 95% cpu use on downloads thanks to pppoe. I think it might be as I'm running protect with a decent amount of cams its just not got the cpu power. Will disable protect, Reboot and give it another try. The next step up if its not protect is a EFG and thats just silly for home use so option 1 or 3 will come into play.

There is a baby jumbo frames hack you can do for PPPoE, I never had much luck with it but I think @RSR has.

Why does Unify not have hardware offload for PPPoE when every other bog standard router does?
Or is it just because Unifi are using slow processors? 1.5GHz isn’t great.

I’m using an Orbi 970 direct to the ONT, no problem saturating a 2500/2500 connection.

Sadly I have never got that to work on the newer units only my original one but since I moved my main ISP to one which doesn't use DHCP on it.
One thing I have discussed with Ubnt is flow control on those ports, as that can cause time-out issues. If you are interested, I'll dig out the commands as that helped my backup PPPoE connection.
Thanks will look into this. Thank you @RSR that would be helpful.
UDM SE is 1.7GHz not that it makes much difference and you raise a valid point. Why on earth is it not offloading is insane. It performs worse than a 90 quid TP link

I've been over this issue with Ubnt in a lot of detail in the past and they have released some fixes from my findings. It's also one of the reasons I know about the flow control issue on the port as they said they could replicate it and they recommended setting those settings.
I'll go back over my old support cases later today and post the commands but they are not permanent as they will need to be applied on every reboot

Yeah just saw the posts - that's pretty cool
I just gave it a test on my failover router and got it working albeit that router is limited to a 1 gig connection for all my VLANs which is not ideal (it is the failover afterall)
Has anyone got PPPoE Active / Passive setup ? I 'can' do it but the solution is not going to be elegant - I've read something on the web about PPPoE routing but don't understand it. I'll have another read

Thinking about this some more, a version of the Aquiss service where you got allocated a private IP address with a /31 routed to it would solve this problem and use the fewest public IP addresses, though still one more per user than the current setup.
You'd configure your router (MikroTik, OpenWrt, whatever) with the PPPoE details except you get a private IP allocated as your 'WAN', you then put the public /31 on the LAN side of your router and sit it in front of the Unifi gateway.
From what I remember from years ago, the UDMP and SE were crippled around 600Mbit to begin with, they improved things to get to the current state, but it's still all software driven and single threaded. Your options for a faster profile are basically offload PPPoE to another box with hardware acceleration, move to an ISP who uses DHCP, or suck it up. Ubiquiti seemingly aren't able to move this to hardware and rather than be up-front with numbers in the marketing, just use a PPPoE speeds may be slower statement when talking about maximum NAT and IPS rates.
Yeh I think it’s capping out about 1350 for me due to running protect and a good amount of cameras so also hitting the cpu. Most users getting 1600 to 1900 are using udm se purely just for network only. I might just keep the udm for protect and get a different router. Been the kick up the butt I need to separate the two.
my 18 months is up with Zen. Been a problem free experience throughout. Half tempted to get the 1800 down/900 up service this time round but I'm pretty sure my current network setup wouldn't make use of the additional speed, and changing it all would be a royal pain in the backside (and expensive).

Going 2.5g or 10g may not be as expensive as you think also If you've got a DIY network like mine then you'll find it's easier than you think.
If however you've been lazy and are using branded junk like ubiquity then I see your point
Budget 2.5/10Gb has been a thing for at least a decade at this point, first it was linking servers direct with older 10Gb cards, but with the recent advent of genuinely inexpensive and decent quality Chinese switches supporting SFP+ and 2.5Gbe, its now a no-brainer, combine that with 2.5Gb and 10Gb being possible over decent 5e and nobody debating an upgrade to a multi-gig fibre service should be worried about the cost of upgrades, the monthly on the connection will cost many times more each year.
