Hi All,

Recently had our internet upgraded by BT to 5.5mb. Getting around 800kbs download speed from microsoft.com, upload seems to be around 40kbs.

Use to be on 2mb, and with torrent download (all legal) pretty much always got around 200-230kbs download spead.

Now, i was expecting a massive speed increase, but it seems my download speeds on torrents seem to be restricted to no more than 40kbs.

Im using utorrent and my settings are as followed (i thought i had them set up right)

I have correctly forwarded port 49176, and utorrent shows a green tick. So i presume that area is correctly set up..

max upload rate 30kbs (set this as the max)
Global maximum number of connections - 400
Maximum number of connected peers per torrent - 60
Number of upload slots per torrent - 7

I have also changed the net.max_halfopen setting to 80

and change the half open tcp settings to 50 (cant remember what this was over the top of my head) but it said it should help.

Any suggestions? or is it simply my upload limit restricting the download?

More like BT traffic shaping your connection.
i.e. When they detect torrents being downloaded they limit the speed you can download them at.

BT don't limit torrent.

But then again, they might if you don't encrypt.

But saying that, they might limit it... I'm only on 512k so I wouldn't notice.
 
i didnt have encrpyt enabled, i enabled it and ive seen up to 500kbs down, so i guess its doing something!

no, now unless your tied into a NDA and can't tell me what you know as far as I'm aware BT do not traffic shape, I've spoken to many BT enginers and they have all told me the same.

Edit - also the fact that I'm with BT and have speeds of 200kbs+ on most popular torrents suggests that something else is wrong, try limiting you upload speed to 12kbs instead, I know its low but it seems to work well on mine.

utorrent, download settings i think, would tell you precisely but the second i run it on campus UEA might slap me with a nice fine...

Could I have some more detail on the "encrypt" thing please :) ... is it in router or uTorrent ? Thanks

In utorrent. Whereabouts it is in utorrent's settings depends on which version you are running - on utorrent 1.5 which I use (not the latest version) it is in the Preferences > Network section. Put encryption to enabled or forced (if the former doesn't work, use the latter) and tick 'allow incoming legacy connections' or you'll only be able to connect to other clients who are using encryption.

It pushed my speeds up from a piddly 20K/sec or so on Freedom2Surf, to maxing out my 2Mb connection at up to 230K/sec so it does work \o/
 
I am pretty much having the same problem with my bt connection :(

I can't get over 30k at night

But in the day a whopping 300k :D

I have just fixed my firewall ( Ports ) So i will see how it is tonight ;)

bt do traffic shape. fact. :D

i don't need an engineer or bt themselves to tell me whether they do or not. like david above, my torrents do slow down at peak times and they are fine during the early morning/day. not that it bothers me one bit. i'm a patient sort of guy. :p

at least it's not 20kb/s 24/7 like it was when i was with pipex..... :D

Its only recently my downlaods have been going slow :) - i think it was my firewall ( After reformat )

I dont think BT traffic shape

I think that's what the Fair Usage Policy is for :p :o

4. We may also take action to manage network capacity during periods of peak demand, please refer to www.bt.com/broadband for more detail.
 
It's quite stupid enfocing both a cap and traffic shaping policy. I see it, if your capped at 30GB, thier basically saying you can do what you want, when you want as long as you don't hit the cap ie, use the bandwidth how and when you like. Now the trouble with uncapped service is that a lot people download 24/7 due to the fact that they are uncapped which gives most people at daytime some performance issues (as 'most' people browse then and not at 4am) which is why a lot of serivices have traffic shaping usally at the day time or 24/7 (like I think Pipex still do) having both isn't really a good idea

Always remember if your having torrent issues try them on a different computer (that'll determine if it's the computer or internet) if it's the computer a quick mess around with the torrent client or maybe a change in client should fix it. If it's the internet reboot your router, or even reset might fix it (also update firmware - my internet used to drop day-after-day and cause me sleepless nights, since I updated the firmware it works like a charm). If both fails try giving the lovely people at your ISP a call asking whever they enforce traffic shaping, capping, p2p throttling (if so your out of luck) if they anit enforcing these it could well be a 'unhealthy torrent'.

Hope this helps.
