Difference between TBB upload speed and BT Wholesale view


[link to this post]
 
Hi,;

I queried a query with my ISP, Plusnet yesterday over upload speed available on my line,. TBB has been showing this as ~1.8Mb/s ever since I took their fibre service in 2015. Plusnet upgraded this on Oct 2017 with a degree of fanfare, to 8-10Mb/s but my TBB speed tests have never shown this.

Today I ran the BT Wholesale speed test and - lo and behold - it's come out as 10.78 Mb/s (earlyish morning and I guess the network's quiet!). Download speeds are pretty much in agreement between the tests.

Anyone have any ideas why there would be such a distinction in the upload speeds, please?

Here's the TBB link for a test just before the BTW one.

And here's the image of the BTW result

Regards,
Ian

Did you go on to do the additional test on BTW? It provides more information.

p.s. I'm on 55/10 and I just got 7.9Mbps on TBB and BTW additional test showed
"Upload speed achieved during the test was 9.23 Mbps
IP Profile for your line is 10 Mbps"

Hi Longedge,

Just reran the test, and looked at the additional details as you suggested. Results similar to last time in terms of upload speed.

Results here...

Regards,
Ian

I guess that perhaps the BTW test results include the network overheads in the final figure whereas TBB results don't but that wouldn't account for the huge difference. It'll be interesting to know if there is an explanation smile

Best explanation

BT Wholesale have IP profile set to 10 Mbps but the Plusnet mirroring is set at 2 Mbps still.

I did have the old 40/2 provision in mind but then couldn't understand why two speedtests done at more or less the same time would come up with different results like that and so discounted that explanation.

Andrew,

Thanks for your post - not sure I completely understand the point about mirroring, so please can you point me at something which explains that?

Ian

BT Wholesale traffic may leave the network before the effect of the Plusnet throttle appears, that is my reasoning

I would suggest that you post on the PlusNet Community forum, perhaps include a link to this thread.

The probability is that your account setup needs correcting and posts on there are monitored by support staff who generally speaking act pretty quickly especially on something easy like this smile .

The TBB test looks very much like a 40/2 service connection, how you are seeing higher upload on the BT test is rather odd. I must admit the BT test is usually wrong for my upload speed but generally it is much lower than my actual speed!

Edit: Just tried the BT Wholesale test and it doesn't complete using Edge browser, just stays downloading. On Chrome it gives a download speed but zero for upload, it never seems to work properlyfrown
