Minimal smoothing on the labs to make any 'software' interactions more visible.

Copied. The only way now I can see any 'history' is to use your link when I am logged in as Flash still does not load.

Other problem I have is that the same behaviour is exhibited again now, using the non-flash test, where the single thread starts 'slow' and on repeated tests climbs nearer to the multi-thread figure. Problem is I cannot paste more than one test from a sequence as each one tells me I am viewing 'someone else's test' (although logged in) and only lists the last test done.

Here is the next test

Out of interest after OR 'work' today my sync has gone from 43 to 49, although speed has not yet changed.

The non-flash will always say 'someone else' as they are not currently linked to your profile, once a site makeover happens this will all change and the moans and groans go away

On the single thread, the traditional response would be you have the RWIN badly configured, but if on the new Plusnet network it may be they have something configured wrong in their part of the network.

Your IP Profile should have changed, visible in the Further Diagnostics of the BT Wholesale Performance Test, (ignore the red instructions, just say yes), as per my post earlier, but Plusnet hold a slightly lower copy of that in your Current line speed, which they use to limit your speed. That only updates three or four times a day.

Check it now, and if it hasn't changed by tomorrow get them to update it. The auto update does occasionally fail, but the notification of a new IP Profile from BTW only arrives once. So if it has failed, it will stay that way until the next IP Profile change.

RWIN badly configured

- how do I check that?

but if on the new Plusnet network it may be they have something configured wrong in their part of the network.

- no, this phenomonen has been happening for months, well before any PN change.

RS - nae wurry! I am well onto that...

OR work now complete and so far no noise on the line and speeds improved. I have also, after much procrastination, moved my home plug circuit onto the same ring main with good improvement.

Speedtest still showing dramatic uplift of single thread speed on second test.

Still hoping someone will tell me about RWin?

Those speedtests do not look great. Congestion of some kind at play here?

I always always get basically an identical speedtest on this forum. Certainly do not get these improvements etc like yourself. I think it is just by fluke.

Fair enough, it's your test and whatever software interactions means may be a valid reason, but it does make normal connections look jagged and sometimes leads to crazy peaks way above what the line is physically capable of. Even "normal" tests burst over line speed yet the text says

The burst speed figure shows the speed your computer and connection sustained for a short period during the test.

Well that's not true - my computer can not send faster than my line - it's just that with low smoothing plus measuring using tcp you see bursts as it is expected that a normally functioning set up will drop packets - as it should, unless you have some really extreme buffer bloat/atypical tcp settings.

Though you've had the issue for longer than the recent Plusnet problems - any testing now may be misleading due to them.

On the rwin - if that were too small/window scaling was off it should really just cap you at a constant speed, but your results are stranger than that.

If possible testing using a different PC/device connected with eth to see if it's better would be the first thing I would try. If you haven't rebooted your router for ages try that. Maybe just trying with a different browser could be a start.

To see your tcp settings you could post the output of -

Though especially on Linux the rwin results (as is noted) are a bit meaningless.

Ta legume - I was under the impression that RWIN tweaking was a thing oif the past in Windows10?

Certainly since my line improvement I have a significantly faster 'first pass' on the single thread (it staerts at around 20 and works up to the mid 40's, then on the second pass - wham straight up to the mid 40's. Multi-thread consistently high 40's.

(Not going to talk about PN's problems of yesterday as I have sent a red-hot snotogram to Andy about the CS aspects of it....)

Test on laptop via Wireless to same router is much less varied, starting at 20'ish with a slight pick up on test 3 to the multi speed of mid 20's. i wonder if there is something adrift with my NIC on the mainframe?

Re TCP settings - Billion 8800NL - where do I find what you seek please?
