City Fibre

Yes it's a rural broadband project, I believe that's upgraded our area. I am the first on my street, at least who's gone for it. Had two days worth of installers come out, and a few neighbours inquire what's going on etc.
https://fibreheroes.co.uk/ this is the website. I can only go for the selected firms on this list, so it's a bit of a stab in the dark. Can only use their router, which is OK, even though it looks like a PS5 ha.

Really happy so far, but will drop them an email about the upload. Sorry, I've messaged in here as it's not the same company

you can use your own router with befibre . i use a d-link
 
Scheduled maintenance in my area this evening, 00:01-06:00, interruption possible - this will be a good test vs my previous provider who never stuck to schedules.
 
I'm after a bit of help with my City Fibre connection. I'm using my Linksys WRT 1900ACS with OpenWrt as my router, as the supplied TP Link Archer C6 is only an AC1200 router as opposed to the Linksys being an AC1900/ However with OpenWRT on the 1900ACS I can not get anywhere near the 900Mbps download. It tops out around the 540Mbps level. Upload I get into the 800Mbps range so that's ok. The Archer with the stock firmware can get up to the 850Mbps levels (according to speed tests that is. I am using OpenWRT as am using DoH and Adblock at the router, so don't want to go back to stock. Any ideas on if the OpenWRT overheads are causing the issue or if its the hardware. On paper the 1900ACS is the better & more powerful router.
 
The ISP is Octaplus, and my CPU load from the onboard data is negligible.

0.54 peak on a dual core does suggest one core is being loaded up. You'll need top or whatever OpenWrt exposes to see what process is doing it.
 
Ok, so it would seem its the IRQ steering pushing all traffic on Eth0 to CPU 0, as ksoftirqd is maxing out at 50%. I've installed IRQBalance, but it does not appear to be helping. and for some reason i cant force the traffic via the SMP_Affinity config as i get an I/O error when trying to amend the files.
 
Here are my tests for Qaud core cpu's just to give an idea

Code: 
Here is an example for you on initial load of the cpu which is 95-100% on some cores and then settles to around 60% from one router to another while testing tcp/udp across my network.

Local-cpu-load=ARM64 Quad core@864MHz
Remote-cpu-load=ARM64 Quad core@1800MHz


tatus: done
      time-remaining: 0s
    ping-min-avg-max: 182us / 269us / 416us
  jitter-min-avg-max: 0s / 25us / 150us
                loss: 0% (0/200)
        tcp-download: 929Mbps local-cpu-load:93%
          tcp-upload: 919Mbps local-cpu-load:62% remote-cpu-load:58%
        udp-download: 940Mbps local-cpu-load:41% remote-cpu-load:40%
          udp-upload: 957Mbps local-cpu-load:57% remote-cpu-load:28%

And here is what is happening while testing, these stats are pulled from the ARM64 Quad core 864MHz router.

Mikrotik RouterOS but It's a big learning curve, lots of funky tools though.
One of these https://mikrotik.com/product/cap_ax
One of these https://mikrotik.com/product/hap_ax2

When I upgrade to City Fibre I'll be adding one of these.

RB5009UG+S+IN | MikroTik

The ultimate heavy-duty home lab router with USB 3.0, 1G and 2.5G Ethernet and a 10G SFP+ cage. You can mount four of these new routers in a single 1U rackmount space! Unprecedented processing power in such a small form factor.
mikrotik.com mikrotik.com

I hear good things about small form factor/mini pc's, but I couldn't advise on any though.
 
I like the look of these MikroTik devices, but they only have 1 2.5g port or higher, so they are not that future proof. so if in the near future CityFibre goes higher than 1Gb. there is no point using it as the rouuter wont be able to push more than 1Gb due to the port limitiation.

They have plenty of 10Gbps+ routers too, mostly in the CCR range
