Hi Sam, All;

Still investigating - From a hardware perspective we have the same network kit in NZ as we have in LA/Sydney. Our Speedtest VM infrastructure/Configuration is the same across the fleet. We are continuing to capture logs/data and work with out vendors to work through this. As per the comments above, this will take some time to understand, investigate and work through this. This for working with us and for your patience. Depending on how and what we test, we see significant differences in reported speeds which further complicates this. :-)

Nick.

SamF:

Speed to the 2Degrees host is brilliant - full line speed:

But I disagree that 'that's the link I'm paying for'; the point of the Internet is to connect you to the world, not just your ISP! :)

Anyway, I don't want to get into a discussion about that; I'm interested in what others are seeing upload speed wise to international locations.

That is exactly what you are paying for. When you sign up to an ISP you are buying a tail connection into their network. If 2 Degrees are letting you upload data to them at the full speed then that is a good thing. If you dislike the networks performance when they peer with other providers then consider changing. In my opinion 2degrees have done pretty well so far.

Who 2 Degrees peer with and how they advertise routes is up to them. This is beyond your control. If you need guaranteed network speed to particular places then I suggest you purchase a service which will guarantee you those speeds to those locations, however you will find they are expensive. Otherwise your traffic is going to travel the paths your network provider peers with, with other traffic that passes over their network.

You might find to get to some of these locations on the other side of the world your traffic might pass across multiple 3rd party networks to reach its destination.

Thanks for the update Nick, I appreciate the info and the ongoing efforts to get this sorted.

Hi All,

As previously mentioned and shared, we have been performing significant testing across our network to validate the results we were seeing on the recently deployed speedtest servers in Sydney and LA. These servers were deployed to validate the performance we have and are seeing across our network with the view that we can continue to leverage these to tune and see issues on an on-going basis.

In parallel we have worked with our hardware vendors, upstream providers, and looked at how these servers have been deployed/provisioned, associated configurations on servers and the network to ensure they are performing as expected. All of our Speedtest servers are deployed in the same fashion with the same amount of resources (CPU/Memory/Network connectivity) and configuration.

We have seen from testing within NZ working with a number of customers that depending on what you are using to test with, your results may/will vary depending on the NIC Drivers/Operating System/browsers (IE/Edge/FF/Chrome) etc.

e.g.: https://www.geekzone.co.nz/forums.asp?forumid=85&topicid=236439&page_no=5#2042056

https://www.geekzone.co.nz/forums.asp?forumid=85&topicid=236439&page_no=5#2042748

For international testing, we have leveraged a third-party webserver in NZ (Nginx) and a Debian 9 Linux box using Waldolf (LA Speedtest server) and Statler (Sydney Speedtest server) as client system for the purposes of testing back to UFB services.

The Aria2 client https://aria2.github.io/ was used on both systems as it supports multiple instances in parallel.

aria2

aria2.github.io

aria2 is a lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. …

The following is a sample of the testing completed to give you an idea. Depending on the time of the day, speedtest server load etc., results may vary.

Using the command aria2c -x 8 URL, we were able to achieve the attached results for Sydney and LA. For Sydney, the average speed for downloading a 4.8Gb file for this test was 48MiB/s which is approximately 400Mbps; For LA, the average speed was 43MiB/s approx 360Mbps. Both achieved peaks above 54MiB/s.

NZ <-> Sydney

NZ <-> LA

We are not sure why the results of the speed test using Speedtest appear average for some uploads. The only conclusion we can come to is that latency and the way the application manages this maybe a factor. We have reached out to Speedtest to see if they will work with us to further investigate this – which they may or may not choose to do.

Thanks for the update @NickMack

Those are certainly interesting results and proof that at it is at least possible to get good 'upload' speeds across 2D's international links in some circumstances.

My initial upload issue actually related to backup services as I was testing the speed of various options but was unable to get anything above 5MiB/s to anywhere internationally. This started me down the benchmarking track.

Given that we have also tested with nperf and the BackBlaze speedtest plus I have also tested using a number of other internet speed test sites, all with similar results, this issue doesn't appear to be limited to just speedtest.net tests.

Here's hoping you can get to the bottom of the issue!

Hi SamF,

I guess it depends where you are testing to/from, the above testing is on the 2degrees network which is obviously something we control. When it comes to off the 2degrees network, there are many elements out of our control. Businesses/hosters make their own decisions on where their servers/services are located and what their connectivity options are.

Absolutely, I understand that there are many variables involved in determining what speeds are achievable, but my point is that I can't get anything uploading at speeds greater than 5MiB/s, not even multiple torrents seeding to hundreds of users at a time.

Also, I'm talking about big names in storage; Google, Backblaze, Dropbox etc, so I'd expect them to have their systems sorted enough to allow better speeds than I'm seeing.

Again, I've tested uploads on a different ISP and got full line speed (in this case 100mbit) upload to Google for instance, but the same test from my connection is significantly slower.

I'm not sure what has changed recently with this issue, but I am now able to get better speeds to LA (the Sydney Speedtest server seems to have disappeared).

More important than the actual upload speed result is that fact that the speed is now continuously climbing throughout the test rather than peaking mid-way through. Based on this I suspect that if a longer upload test was run the speed would be even higher.

I am planning to try some real-world upload tests soon, so I'll share my results with that here.

Hi SamF,

There are changes going on all the time on the network - Adding lags/capacity, new POPs, as well as on-going upgrades etc. :-) In terms of the speedtest server is Sydney, there's currently an interface issue with that box causing BGP flaps, once resolved it will be added back into the mix :-)

Um, ok; fixed! :D

This is for a multi-threaded backup upload to the west coast of the US and all figures are in MegaBYTES per second!

Nice work guys!!

Can confirm - things are looking incredibly good now.

Just seems Speedtest is a little poked now but real world performance is excellent.
