Hi Team, we are watching this thread but don't really have any conclusive information to share as of yet.

That being said, some upcoming maintenance is being planned which may assist with those who are experiencing these issues (potentially) and will post here once that's booked.

Rate limiting to 100Mbps upload has made no real improvement in my case - also in Wellington.

I am currently testing and monitoring it running on VLAN10 with DHCP - accumulating more results over time.
Initial results are very much the same as Untagged DHCP/PPPoE.

Excited fingers crossed!

Hi,

Can I get some advice please.

I tried the suggestion to rate limit uploads to 100Mbps - no improvement.

I tried hard-coding the destination speedtest server to be Vetta Auckland (34112) - seems worse for me, here in Wellington. I have reverted back to the Vetta Christchurch server (42535) for scheduled speedtests - let's see what that does...

Is there a server that has a more optimal connection that I should be using?

The last result when speedtest looks for the 11 'closest' returns this order:

   ID  Name                           Location             Country 
============================================================================== 
 42535  Vetta Online                   Christchurch         New Zealand 
  4954  One New Zealand                Wellington           New Zealand 
 11326  Spark New Zealand              Wellington           New Zealand 
 46550  NOW                            Wellington           New Zealand 
 41578  Zylex                          Wellington           New Zealand 
 43554  ACSData                        Wellington           New Zealand 
 61718  Voyager Internet               Wellington           New Zealand 
  3797  Inspire Net Ltd                Palmerston North     New Zealand 
  2336  Amuri.net                      Culverden            New Zealand 
  2025  Primo                          New Plymouth         New Zealand 
   465  NOW                            Napier               New Zealand

Thanks in advance for any advice.

I find that Chorus Fibre Lab Auckland good for testing server id 28463

Thought I might post an update, there was a marginal improvement over the last 12ish days, but then sometime over the last day or 2 something has changed to have fixed all my issues.
Not sure who it was but thank you internet Jesus! - as they say time heals all wounds.

One thing I did do, though not sure if it is related, was updated my IP in all the GeoIP databases I could find (such as Maxmind) to reference my actual city.
Pings are back down to 2ms, uploads are stable at 500+ and downloads stable at 925+/-

Take a look at https://geolocatemuch.com as Quic/Vetta publish geofeeds. Shouldn't impact your connection though, that's just a weird issue.

Likewise, I am now seeing a consistent throughput on the connection!

Latency is far more stable as well:

My Windows Server still has upstream throughput issue - none of my other machines do.
So need to investigate that side.

Thanks for that, I had tuned it as well as Windows will allow.
And it is running a Mellanox adapter so luckily doesn't suffer the same issues as some Realtek chipsets.

I wonder if a Windows update reset the tuning.
Or it's possible dust got in when I had pulled the SFPs and fibre cables to originally troubleshoot.

I updated my post there (again). Thought i had fixed it, but still looking for the little network gremlins running around somewhere. Very odd issue

I have been plodding away with this as my time allows.
I have narrowed it down to just the TCP stack - because the Windows TCP stack spans both IPv4 and 6 it affects both.

My suspicion is that Windows TCP stack is trying its hardest to do what it can.
Tweaking from defaults improves the results but does not fix the issue.

But I think it is failing to manage / handle what might be buffers within Quic.

Windows 10 is the most effected.
Windows 11 is effected - but less than 10.
Linux by default is not.

I am spinning up a fresh Win10, Win11 and Linux VM to investigate further.
