VIVID 350 Slow Peering and Amazon Prime Video Unusable...

So over a decade ago I told myself I would never go back to Virgin Media after years of poor service. I've paid for VIVID 350 but before you scream wolf, they state 362mbps average meanwhile I have 100 -  200 Mbps, I might as well be paying for VIVID 200 but then... I would still have lag.

  • Amazon Prime Video I get NOT enough bandwidth constantly every 10mins
  • Counter Strike GO and World of Warcraft ping spikes
  • Poor single thread downloads
  • Upload speed 10-14 Mbps

As recommended by Virgin to use pointless multi-threaded speed tests that they no doubtly use Smart Traffic Management to invisibly prioritize speed tests, here are some pointless test results:

  • Speedtest.net (200-240 Mbps) Faster than others but I suspect Virgin Media is using Smart Traffic Management to invisibly prioritize speed tests.(VM Bristol, GigaClear PLC, etc)
  • Fast.com 180 Mbps (8 Threads)

---

I'm a network administrator with access to many online hosting platforms so here is some real world tests using run over several days at random with an average:

  • Microsoft Azure CDN (Akamai) 152 Mbps
  • Microsoft Azure CDN (Verozon) 201 Mbps
  • Microsoft Azure Cloud Storage (UK West) 138 Mbps
  • Microsoft Azure Cloud Storage (UK South) 180 Mbps
  • Microsoft Azure Virtual Machines (UK West) 174 Mbps
  • Amazon Cloudflare 300 Mbps  <-- Acceptable
  • Amazon S3 (EU West 2) 240 Mbps
  • Amazon S3 (EU Central 1)  173 Mbps
  • Amazon S3 (EU Norton 1) 152 Mbps
  • Google Cloud Storage (EU West 2) 185 Mbps
  • Google Compute Engine (EU West 2-A) 174 Mbps
  • Google Compute Engine (EU West 1-C) 242 Mbps
  • Cloudflare CDN 197 Mbps
  • Oracle Cloud Compute  212 Mbps
  • Rackspace Cloud Files (London) 157 Mbps
  • Rackspace Cloud CDN (UK) 290 Mbps <-- Acceptable
  • Cloudhelix Vmware Cloud Hosting (London) 92 Mbps <-- Very poor
  • CenturyLink Cloud Storage (Germamny) 133 Mbps
  • IBM Cloud (EU DE)  34 Mbps <-- Very poor
  • Vultr (London) 116 Mbps
  • DigitalOcean (London) 127 Mbps
  • CacheFly 330 Mbps <--- Ideal
  • Linode Cloud Hosting 328 Mbps <-- Ideal

As you can see the results are a mix bag some are up to standard while others are not - to me it looks like poor peering from network to network since the majority of these networks can handle 10 Gbit and beyond.

All tests are above are double threaded SSL downloads and had I opted to use single thread downloads the test results would be far worse.

Test setup: VM Hub 3 in modem mode connected to Ubiquiti Router using CAT6 23 AWG cable and the testing machine is connected to the rounter using CAT6 23 AWG 100% Copper Stranded  Cable. Iperf3 has been tested on the internal network and speeds are in excess of 967 Mbps.

---

The most annoying problem is the lag on games and the Amazon Prime stopping and complaining about Bandwith. The Amazon Prime is hooked up to a TP-Link 1200 Mbps Powerline adapter at the connectin speed of 567 Mbps but using Iperf3 I can see the average is around 243 Mbps and drops no lower than 199 Mbits which is far beyond the requirement. I had Amazon Prime with BT 76 Mbps (71 Mbps realisticly) and had no problems, same setup, just different provider.

As much as I know about networking docsis 3.0 is not strong point and here is my stats from my hub 3:

Re: VIVID 350 Slow Peering and Amazon Prime Video Unusable...

There are issues on the cable network serving you. You should not have any post RS errors or T3 timeouts across all channels.

This makes the various peering tests misleading at best and futile at worst.

VM are not using smart traffic management to prioritise speed tests. Those are using more threads so TCP itself causes apparent prioritisation.

Sorry, are you saying I have issues with my signal to the house and that I need to speak to VM?

Re: VIVID 350 Slow Peering and Amazon Prime Video Unusable...

Basically yes that's what ignition is saying. The RS errors could possibly be "historical" - can you reset the counters in your Hub settings? If not, switch it off for a few minutes and restart it - check they are cleared to 0 and then monitor them over the next 24 hours or so - see if they start to build up.

Re: VIVID 350 Slow Peering and Amazon Prime Video Unusable...

Hi jbrennand, thanks for your reply, Friday I was completely out of internet until 4pm from the early hours and the network status reported changes in the local area, I was hoping that it would address my problems but after several days, lag is bad... I'm really regretting moving from BT to Virgin now.

Looking at my RS errors, they were reset as you can see and can see that they are climbing, I'm unsure how I report the issue since they I suspect they are just going to do multithread speed tests when its my single thread and ping

Re: VIVID 350 Slow Peering and Amazon Prime Video Unusable...

Hi SimonHayterUK,

Thanks for getting in touch. I am sorry to see you have had trouble with your connection.

 

I have taken a look and things seem to be ok from this side. It may help to try the following so we can rule some things out:

Pop the hub into Modem Mode with the computer in Safe Mode with Networking at different times of the day.

Try on separate devices.

Check Ethernet cable. Make sure it is new / up to date. (Cat 5e or above).

Make sure device is capable of agreed speed.

Check wireless card slide.

Take care.

 Emma
