100mbit and Speedtests

Got upgraded to 100mbit today however the service has been a slow especially browsing. Contacted Virgin who connected to my PC remotely and tested the speed using their internal speedtest site. Their internal speedtest showed 102mbit download and about 4.72mbit upload.

Using any other speedtest site such as Speedtest and Thinkbroadband then I get a completely different value... between 19mbit - 35mbit. Which is right?

They all can be right,as the other testers will require Virgin Media to have good links out onto the internet too.

Tried downloading some files from machines inside the VM network, to check the figures from their tester?

Good idea. An iso from this page, for example.

Thanks I downloaded the x86 server iso from the Ubuntu page and got about 11.2mb per second download speed... It really was quite quick....

I find the namesco and speedtest.net Maidstone Custodian Data Centre give good results.

Max i've ever got from this site was 97.2mbps which is the highest it's ever gone for me - still brill

Tried the namesco one and I got 99383kbps....which is fantastic! I'm impressed. Could the earlier results be the result of traffic management from Virgin?

Congestion on a UBR would also affect stuff on the virgin internal network.

Ok, thanks... I'll monitor it closely today....

I'm going to see another speed increase to 120mb....I can't wait now...

If you tested just before your post time - Thu 26-Apr-12 22:50:17 perhaps your local torrent freak had shut down his client?

The thing about congestion is that it varies. Sometimes over very short timescales.

Lol! Quite possibly.....and there was I hoping I was the only Virgin customer on the block.... If only!

Upload has never been a strong point of the DOCSIS architecture

probably peering/routing issues been highlighted by the slow speedtest.net

I am also curious tho if the internal VM speedtest gets any favourable treatment on the UBR.

So far every single test I have done on it has been full speed and I will keep doing more tests from now on it whenever I see slow downloads.

A excellect test. I don't see much in the way of slowdowns these days apart from STM. Mind you if DOCSIS3 can't deliver the 10Mbps I downgraded to then things really are bad.

well I have only tested on it since I got new DS channels added so generally my performance was already improved anyway, but I have since seen a couple of small slowdowns which werent present on the VM internal speedtester.

Nope.
