Jelv, the DSL reports test is a single thread too, that's why I asked the question.

Perhaps a routing/peering issue?

I was migrated away from Vodafone on Thursday, seen some improvement, but something still isn't right.

Cloudscape are investigating further.

In that case the later half of the test must have hit a period when there was a bit of a break in other users downloading. If you run repeated dslreports tests do the graphs and results vary a lot? That would indicate somewhere along the connection between you and the speed test server something is running near full capacity and sometimes over.

In dslreports speedtest preferences you can set the number of streams. Have you tried running multiple download streams to see if that shows a similar difference to the tbb x1 and x6?

It might also show that the issues are not just between exchange and provider, but provider and wider internet and the various routes leaving provider may have varying levels of congestion on them.

Thanks - absolutely right. I've modified my post for clarity.

Hi Andrew,

We have already addressed this I believe in this thread. We have absolutely no issues between our interconnects with the various suppliers and the wider internet.

We did briefly have a load balancing issue on Feb 14th which was addressed and remedied the afternoon it was identified.

We are not seeing congestion on the links from the providers to us. But we are seeing congestion on a very few individual connections most of whom are already participating in this thread.

Are you saying it is the users own traffic causing congestion? Or is there something else that can cause congestion on an "individual connection"?

Hi Ian72,

No,of course we are not saying that. We are saying it looks like congestion on a link somewhere between the user and where the traffic hits us.

We have been gathering data and this is being passed to the carrier concerned.

OK, fair enough. Backhaul link with your wholesaler rather than links from yourselves to peering.

OK so a little update, my connection was moved over on Friday, I've been at home some of the weekend so have been able to do a few tests, there is still some congestion, but nothing like the previous issues I was getting.
Lowest speed I've seen is 17mb, but the majority of the busy periods it's been around 30mb to 70mb, i'd say averaging out at around 40ish - 50mb.

a few tests over the weekend and Monday night can be seen below.

It's not perfect, but much better than it's been, the service is usable, I'll update over the next week or so.
