RunningMan:

is the R6S capable of that throughput over PPPoE? A brief Google search couldn't confirm either way, but just because a router has 2.5Gb/s (or greater) ports, doesn't mean it can saturate them under all conditions.

It has no issues with downloads - as is the same with the UDM - but both struggle on uploads.

Should PPPoE affect the upload more than the download @RunningMan?

Anecdotally, it does, but I'm not sure why. Only a guess, but perhaps inefficient code carried over from many years ago?

Can you check CPU usage per core on the R6S when testing? PPP code can be old and not written to take advantage of multiple CPU cores, so if 1 core is sitting at or near 100% that is likely the issue.

I can confirm, we’ve tested the ONT in RGW mode and it can do PPPoE with the 2, 4 and 8 gbps variants - no issues.

Full transparency though - stop sell of RGW mode is 31 October 2023 and full withdrawal 31 October 2024.

The ONT RGW did indeed run at wire speed from my testing (basic features). PPP on my Mikrotik CCR2004 of course also runs at full 4G (no 8G at my exchange) with about 30% cpu during the test (less than 1% normally). Obviously a CCR is not your average home router (hard to make quiet and not cheap), but yes it can be done.

Oh, and the ONLY way to get consistant speedtests on Hyperfibre is to run a Linux machine using the CLI. Windows on exactly the same hardware (or a VM on the same server) just does not cut it. You can have a 10K gaming setup running windows and still not get full rate speedtests.

We don’t find that to necessarily be the case.
We have used browsers on both Mac and Windows PC’s to get consistent multi-gigabit Speedtest results.
Admittedly the Mac was more consistently able to get 8gbps results, and sure, it’s technically Linux, but we were doing it in a browser.

But this thread is about router capability, not necessarily multi-gig speeds to an individual end device

To be honest I'd be happy with "better than UFB" upload speeds but whatever config I try on PPPoE seems to kill them... 😢

Come on @BMarquis! MacOS is Unix based (Darwin). No Linux there! :)

But I've always had problems with Windows in regards to high speed connections. It just simply isn't as good as Linux (or Unix) IMHO.

@noroad - So if I was to run up a test rig on a Linux Live image, create a PPPoE connection, and plug it's 10Gb port directly into the ONT's 10Gb port* and use the CLI to speedtest, this would be a good way of removing everything else from the equation?

Do I need to adjust MTU or MSS settings on the PPPoE connection?

*Yes, I'm aware of the security implications - testing purposes only

Once you've done that, introduce the R6S and assess the impact.

noroad was talking about where the linux machine is behind a router

If you use a live image and terminate PPP on that PC - You still have the issues of whether or not the PPP application you use and the hardware are capable of PPPoE at multi-gig rates and a high enough packet per second rate.

For MTU - You'll want the PPP payload to fit a full 1500Byte frame, which means you need a PPP implementation that allows the fully PPP encapsulated packet to be 1508 (ppp-max-payload tag, sometimes known as arberg)

Dont forget the vlan tag (vlan 10)

What OS image are you running on the R6S?

I have an R2S. I have found I get the best performance and reliability by using Armbian with a newer kernel, and turning on nftables flow tables.

I've done Gigabit PPPoE comfortably on a RPi4 with OpenWRT, so would expect you could do Gigabit+ with the R6S. If you're using OpenWRT then you will likely need to fiddle with IRQ balance and processor affinity etc. As already mentioned PPPoE on Nix is a bugger and very dependent on single thread performance.

Could someone post the Mikrotik setup for their Hyperfibre in place of the Nokia GW.

I have broadband with Myrepublic.

Thanks
