Bittorrent and ntl
 

How do I increase the speed of Bittirrent downloads on my ntl 750k cable modem. I am only getting 10kbs. My cable modem is connected to my linksys wrt54g by ethernet and then to my windows 2000 pc. I have turned off the firewall and forwarded ports 6881-6889 to my ip address 192.168.1.101. Any ideas?

The speed of your downloads will relate to the speed up your uploads, and also the speeds that others to whom you are connecting are transmitting / receiving.

You will need to balance the number of connections and your maximum upload so that you don't saturate your bandwidth. Too many connections, or too high an upload, and you won't have spare upload bandwidth for the "packet received and understood" messages to also be issued.

If the ntl network you are connected to is congested your speeds will also be limited due to intentional network contention.

Well to start off check your client or get a client with a 'health' rating. (green, yellow, red etc.)

If its green you can then rule certain things out.

Client i would recommend is Azureus.

I am uploading at 15k and downloading at 10k. Shouldn't my downloads be quicker than my uploads? I am using the latest bittorrent 3.4.2.

thanks for your help

Not really, you should find that as long as:
a) Your firewall/router is configured correctly to let traffic through on whichever ports
b) The NTL proxy servers are not caching the tracker

..then you should be downloading at a high speed when you leave the client software downloading for more than a few hours.
It usually speeds up towards the end of the file and it's always best to keep the client window open instead of opening and closing it when downloading the same file - this way you keep your queue position.

Switched to azereus and limited the upload to 8.5k and the downloads increased to 20k.

thnaks for the suggestions.

Re: Bittorrent and ntl
 

Bit torrent is entirely dependent upon the people you're downloading from.... their upload limit may be crappy, or they may have configured their client to leech as much as possible, etc...

A lot will depend on where you're getting your torrents from... some sites are better than others. There is a site that has some elite torrents (Google is your best friend) that always provides me with the fastest downloads, ie 150KB/s no problems.

Also remember that your download speed will vary as your client connects to more and more people. Try leaving your client open for a while before assuming you're not gonna get any decent speeds.

Finally, only download legal stuff ;)

Re: Bittorrent and ntl
 

I've tried various clients and found the speed with all of them was the same until I read somewhere about changing the default Torrent ports (6881-6889) as some ISPs throttle and even block them.


Changed mine to some silly 65xxx ones and bang - it flies - so much so it actually meant I had to replace my Netgear NIC which couldn't handle the load and kept blue screening my PC.

I use the Burst client now, simply because it was the easiest to change the default port settings in.

Re: Bittorrent and ntl
 

maybe try changing it to 6881-6999

Re: Bittorrent and ntl
 

I would go for ones starting higher than that as you only need one port per transfer and you probably won't use more than ten. As 6881 is the default then NTL (if they do) would throtle maybe 6881 upwards. Pick something well above that???

When I used the Azareus BT client, I used port 49152, & had no problems at all.

Re: Bittorrent and ntl
 

tried various torrent clients all d/l same speed but i use azareus as i like the emule like Queue :)
as for ur slow d/l's it could be many reasons but remember just because you have a 750k line dosnt mean u will get that off torrent all the time there are hundreds of people out there like you who can d/l loads faster tahn they can upload ...

Anyone upped the number of tcp/ip connections when running windows xp sp2? Apparently SP2 cut the number of simultaneous tcp/ip connections. My download speeds vary widely, starting off slowly and getting faster as the download proceeds. Currently getting 105kbs on my new 2mb line. See this link for details:--

Re: Bittorrent and ntl
 

On ABC torrent my speeds improve when I specify my IP address, get more remote connections. Don't forget that NTL hide you behind a proxy server, so not all peers can see you.

Technical details may not be correct, but it works for me.

I increased open ports in XP SP2 to 15 or 20 and that improved general surfing performance when using bit torrent.

Re: Bittorrent and ntl
 

I changed my tcpip connections up to 1000 and edited the boot.ini as detailed in the thread above. Cannot notice any difference yet. Take the www out of the link when you click on it. Must be a vbulletin bug.
