It seems to be connection or ISP specific though.

Do we have any comparisons from TalkTalk or Sky FTTC users yet? It would be interesting to rule out WBC, and MSILs etc.

THanks.

It gives 49.1 over 10.2 with a 99% rating.

Correct

The issue isn't Java, but Thinkbroadband's java tester (or maybe the server backing it up).

The most reliable speedtest I have found is http://mcslhr.visualware.com/myspeed/myspeed_line_ca... . It's the only tester that seems to get upload speeds that reflect a good real world site.

Just noticed Zarjaz referenced the same test above. For me it reports 68.6Mb download and 17.0Mb upload (Infinity 2). I understand I could increase upload a little by turning off QoS on the modem. I stopped using Thinkbroadband test when I moved to Infinity; completely useless now. Just reported Speed Down 31483.66 Kbps ( 30.7 Mbps ) Speed Up 3999.75 Kbps ( 3.9 Mbps )

If it was the server why on corporate fast connections does the same server give decent speeds?

What is going on is

1. Some ISPs and traffic management, we don't use HTTP protocol
2. Possible crude per thread management in the WBC network, or BT Retail segment
3. Some testers showing burst speed (or peak'ish)

The updates to the Android tester give some hints for the future

The speeds from the visualware site report figures very close to sustained values I get with 'real' downloads and uploads from good quality sites. (I'm happy to say that mostly I have seen sustained speeds very close to burst speeds on Infinity).

Just tried Thinkbroadband on port 80, same sort of results. Speed Down 32974.94 Kbps ( 32.2 Mbps ) Speed Up 4027.43 Kbps ( 3.9 Mbps ). Maybe your tester uses something seen by BT as p2p?

I trust Seb and MrSaffron to know the network the tester is connected to. The video shows in 2008 it could do 200+ Mbps upload and download - and I've seen 80Mbps upload and download on a corporate connection with AT&T a few years ago from the java tester.

For home broadband - using the BTwholesale WBC network. I'm still looking for reports from Sky and TalkTalk fibre users, or Hyperoptic users, or Digital Region (assuming they're not using WBC) that either have the same issue, or don't have the issue.

It does sound as if BT Broadband's Infinity product is doing something odd. My installation is Weds.

That I think is what MrSaffron has been alluding to - the problem is in the ISP's management. Not every ISP does traffic management as you're aware being a former BEing.

Very much so, as in our protocol is dealt with as unrecognised which means it gets lumped into the p2p cluster a lot of the time.

Quite a nice illustration of how simplistic traffic management actually is, even worse when it tries to identify based on content.
