BT Broadband torrent throttling?

charlie_says

Hello,

Does anyone know if BT are throttling bittorrent traffic? Is there a way to find out (without myself phoning/emailing them - I do tend to download and upload a lot and don't want to contact them from what I have heard on the boards about their customer service)?

Recenlty seen a big drop in my speed on most torrents. Tried changing port to 1720 (forwarded correctly) as I heard its a good one to use since the ISP will assume it is VOIP packets, hasn't seem to have much affect at all.

If anyone could help it would be much appreciated. I will include my settings just in case I fecked them up...

Bit of background info:

Windows XP SP2 (TCP/IP.sys patched to 50 incoming connections as per utorrent.com guides)

I have ADSL PPPoE 1Mb/128kb on ZyZel 660 RTU-1 modem
Test download speed at 853-868kb per sec from irishiptest.ie
Test upload speed at 100-110 kb per sec from same.
Apparently this is due to the PPPoE implementation and you will not get your full rated speed because of this (I have heard, not researched).

utorrent 1.6 settings (assume I have not ticked an option if don't mentioned here):
Connection-
Global max upload rate 10 kB per sec
Global max download rate 96 kB per sec
Port used for incoming connection 1720
Bittorrent-
Global max number of connections 100
Maximum number of connected peers per torrent 17
Number of upload slots per torrent 3
Use additional upload slots if upload speed <90% ticked
DHT ticked
DHT enabled for new torrents ticked
Enable Peer exchange ticked
Ask tracker for scrape information ticked
Outgoing protocol encryption enabled
Allow incoming connections enabled
Advanced options (the rest are defaults except what I have changed below)
netmax halfopen set to 40
peerdisconnectinactive interval 600


My upload speed stays constant at around 8-10 kB per sec on most torrents, my problem is that now (as of about 2 days ago) I regularly get only 15-25 kB per sec downloads instead of previously 65-109 kB per sec. I tend to only download 1 torrent at a time and then seed for a good long time. Also I usually choose only decent torrents to download with a good ration of seeds to peers.

I hope it is my settings, as if it is BT then there is little I can do.....?
