I was talking about download speeds not upload (TBBx1 and HTTPx6 on the TBB speed tester).

You're missing his point. The two meet, however the customer should, going by his upload, be receiving at least 150Mb down, not about 50.

The user in that test has an upload of > 10Mb. There's nothing below 150Mb on VM with that upload. That is not an example of a properly functional VM connection. It looks potentially like one that's being heavily limited by wireless performance.

It's pretty slow to ramp up, too. Wonder if that was done on a mobile phone?

Anyhow, do you know why I am seeing different single thread download speeds between

http://http-speedtest4.thinkbroadband.com/1GB.zip ->12MB/s

and

http://ipv4.download.thinkbroadband.com/1GB.zip -> 27MB/s

MrSaffron says it isn't a problem at TBB's end so what could be the "bottleneck" here?

cje85 what speed do you get from:

http://http-speedtest4.thinkbroadband.com/1GB.zip

It peaked at just 103Mbps and was generally around 80Mbps.

the normal 1Gb file download test from http://ipv4.download.thinkbroadband.com/1GB.zip reached 219Mbps.

So it seems that connections to http-speedtest4.thinkbroadband.com are bring limited in some way which may be causing the poor single thread results on the TBB speed test.

Looks like you pasted the same traceroute twice but here is mine:

Oops - sorry about that.

Looks like your route, outbound at least, is the same for both servers.

Nope - discussing elsewhere.

We've been doing that for some years now, hence why can talk of PC/phone/tablet speeds and estimate effect of Wi-Fi on overall results

How come you have 20 mbps up?

I'm on the Vivid 200 Gamer package.

I've done various speed tests from different servers and made a small collage:

As you can see I can download faster from New York than http://http-speedtest4.thinkbroadband.com/1GB.zip which is very odd.

Can you identify what the cause is for the difference in speeds? All tests were conducted at the time of my speedtest:

Yes it is believed to be down to the way Virgin Media are handling traffic from the two different servers, one going over a more congested route than the other.

As has been said before, the Virgin Media core network is large and various parts of it have congestion

I can varify that this does seem to be the issue, I suffer the same with my Virgin connection, it was worse but Virgin made a little change that made things better but seems that some core network equipment upgrades around these servers regions will be needing/getting upgrades soon.
