Hi All,

 

A few 2degrees customers, including myself have noticed that download performance from the same endpoints is very different when connecting with IPv4 vs IPv6.
File transfers via IPv6 seem to be capped at approx 3Mbps.

 

The purpose of this thread is to gather information that may help with troubleshooting and prioritisation, e.g.
- how many people are affected?
- do the affected people have anything in common?
- are there performance issues with all or some IPv6 downloads?

 

I'm creating this thread because the latest update from support (after being escalated) was that the problem could not be reproduced.

 


It would be great if we could have people respond to the following questions. Please refer to the list of example downloads at the bottom of this post.
A quick way to test with a Windows machine is to uncheck 'IPv4' or 'IPv6' in the properties of your network adapter which will force use of the other protocol. Network adapters can be accessed via the 'Network and Sharing Center' in Windows 7, 8 & 10.
Otherwise, Start -> Run -> type in explorer.exe ::{7007ACC7-3202-11D1-AAD2-00805FC1270E} and hit enter. Find your active network adapter, right click on it, and choose 'properties'.

 


I'll start:

 

Are you affected? Yes - IPv6 downloads from the example URLs do not exceed ~280Kbps. IPv4 downloads all run at multi-megabit speeds.
ISP? 2degrees
Consumer or business connection? Consumer
Internet connectivity medium? Fibre
Where are you based? Wellington
Router model(s) tested? HG659, Custom (pfSense), Direct PPPoE connection to Dell XPS13 9370 (Windows 10)
PPPoE MTU(don't worry if you don't know what this is)? 1492 & 1500 byte MTU (verified)
Operating Systems tested? Windows 10, Windows Server 2016, Ubuntu Server 16.04.4
Do you have an example dual-stack download that performs well with both protocols? no
Are there other example downloads that you can find that don't perform well? We'd be most interested in ones that follow different routes.

 

If you can think of other questions that might be useful, please share.

 

Extra:

 

- It would be interesting to see what happens if anyone is able to host a test IPv6 download on WIX
- Test results from people using other ISPs would be useful to have as well. @hio had the following to say about another GeForce driver download: "pegging lines here, both spark and vf v4+v6"

 


Example downloads:

Hi All,

 

Testing has pointed us to the likely suspect - an issue has been identified with a change in behavior post a Junos upgrade on our core PE's - Change is currently in QA with the change scheduled to be rolled out today.

 

Nick.
