Guys Ive been speaking with Si tonight about this.

Earlier I was on a gateway which was seeing appauling speeds anyhow something Ive noticed and it would be good if anyone has time to see if they can replicate this data.

Earlier on ptn-ag2 I was struggling with http badly..  however the main data Id like to see if anyone can replicate is the following:-

The speedtesters Im using are
BBMax http://www.speedtest.bbmax.co.uk/
ADSL Guide http://www.adslguide.org.uk/tools/speedtest.asp
FTP data: http://ftp://ftp.ukc.mirrorservice.org/sites/releases.ubuntu.com/edubuntu/dapper/ using the ISO files available for download

--------------------------


Gateway:- ptn ag2

AG speetest result:-  1,154.2 Kbps
BBMax Speedtest result:- 2040 kbps

FTP downloads
1 file = 130 KB/sec
2 files = between 1.5 and 3.2 Mbps
3 files = 2.2 - 4.6Mbps
4 files = 3.2 - 5.5Mbps
5 files = averaging 5Mbps

BBMax speedtest result 2086 kbps


[edited to add]
And now my http has just jumped through the roof
BBMax speedtest result 6081 kbps and 6096 kbps.

Speedtest.net results:

Edit: BBMax Download Speed: 5906 kbps
Edit2: AG Downstream     3,842.3 Kbps

Gateway ptn-ag2
PAYG 3000 kbps stable rate
ADSLGuide 1311kbps and 1598kbps
BBmax 2973kbps
FTP varying between 230 - 300 kB/s for single file using Firefox downloader
Using Speedtest.net
London 2258 and 2409kbps
Derby 2908 and 3085kbps
Why the difference I don't know

PTE-AG1



FTP download, between 480 and 520 constantly.

Hi

  I am on pte-ag1

  http://www.speedtest.bbmax.co.uk/ result
Last Result:
Download Speed: 5787 kbps (723.4 KB/sec transfer rate)
Upload Speed: 378 kbps (47.3 KB/sec transfer rate)

One of the fasest ever results 

About 500-540 for ftp download

Hope this helps

I think the major thing I noticed was that opening up more FTP sessions... then the better speed I was getting.  One ftp connection was pretty bad..  but by the time I'd opened 5, then I was near maxing my connection on ftp.

This isnt supposed to happen - its meant to be an overall limit - not xMb per tcp connection.

TBH though I think whatever it was is now over...  earlier things were pretty bad - yet Ive just downloaded on http at 6.6Mbps
(and no Si didnt suddenly give me a speed increase or pref treatment)..  I want to try and get to the bottom of this for _all_ of us.

To add to my post above (which I've updated with AG & BBMax results).

I'm still on ptn-ag2. For FTP I use GetRight which will use multiple connections - to different servers which it can find automatically.

With 1 connection speeds were up and down like a yoyo, but rarely going above 450KB - that was from the server Kitz gave.

With 2 it was fairly steady on about 700KB. 3 was a little better. With 8 I got up to a pretty steady 800KB.

Edit: I am on PAYG - if that makes a difference. I'm also due to be billed on 3rd with plenty of unused allowance out of my 15GB if you want me to do more testing.

I've also attached a complete set of speedtest.net results

Thanks for that jelv.. 
Thats exactly what I was seeing..  and what shouldnt apparently be happening.

[_CN_]

Gold traffic should have no drops but may have a bigger RTT than the Titanium queue.  During peak the RTT will have a bearing on your Kbps.  We are working towards no drops.

[Colin]

RTT?

[jelv1]

You mean all the heavy downloaders have cottoned on to using multiple connections, using up all the central capacity and hence knackering everything else?

[Oldjim]

RTT - Round trip delay time 

[ianwild]

You mean all the heavy downloaders have cottoned on to using multiple connections, using up all the central capacity and hence knackering everything else?

It's certainly worthy of a focus for tomorrow's continued investigation into this!

Personally, I'm also really in understanding better the impact of what I perceive to be be a recent increase in the number of port scans / background traffic / virus generated stuff I see on my connection, (Dealing with stuff like this is the one time when you'll find me agreeing with the idea of port blocking)... I'd be interested to know if anyone else is noticing a change?

As a consequence of last night's tests - I've asked a question about speed testers here.
