There are several ways where you can tweak Xunlei 迅雷 for better download speed. The things that you can do to speed up your Thunder Xunlei download speed are as following:

1. Port Forwarding the ports that stated in your xunlei for both TCP and UDP. To see what’s your TCP and UDP ports are of your Xunlei, go to tools and then option, go to BT and look for the ports(the words are in chinese). For guide of port forwarding, visit www.portforward.com.

2. Uncheck UPnP under the same place(tools -> option -> BT).

3. Set your upload speed below the speed you can get. For example, if your package support 512kbps of upload speed, set it to 40-45kb/s.

4. DOWNLOAD ONE FILE AT A TIME. This is the most obvious tweak. You may see a great change of speed after you stop a several tasks and let only one of them run it.

5. Since it work as a http header, some people claim that forwarding port 80, 8080 and 21 are the best because there is no other http browser using ports beside these 3 ports. I personally don’t feel any differences of this tweak.

6. If you are using Windows XP, set your TCP half open connection to around 100 so that more connections are allowed to connect through your pc. Google “TCP half open connection” for more details.

Good Luck and enjoy downloading!

Yes! we have no choice but to love Streamyx!
If you are a subscriber of ~~ streamyx, you should know how we, the users of TM Net Streamyx feel when we are downloading through torrent. Torrent is totally legal for everyone to use, as long as the materials you upload or download are not illegally copied. But, I believe nobody will care about this. So, lets leave this aside.

Speed? Throttling?
Speed, speed and speed! Everyone wants speed! But for us, the Streamyx users are not getting the speed we want. It’s ok if we take consideration of our economy. We are unfortunately unable to afford the higher technology. We understand it. But, please don’t throttle us… (Based what I know, throttle means something like blocking you from p2p connection.)

How slow you are when you are torrent-ing?
I personally get 1 to 10kbps using Bitcomet, Azureus, utorrent and BitTorrent. How about you? I’m not sure whether you get better speed or not because the possibility for them to throttle you is extremely depending on your location. They throttle the users mostly from crowded place as their bandwidth of that area is not able to support all users.

Best Torrent Client?
There is nothing that is the best. But for us who get throttled by our ISP, 迅雷(xunlei) or Thunder is the best solution to download faster!

How does 迅雷(xunlei) or Thunder works?
(Based on what I understand about this software) Xunlei connects to peers using fake http header, unlike other torrent client which connect to peers directly. Since it works this way, the connection is no longer a p2p connection. It is the same as you download something from a source. For Xunlei, a peer is equal to a source, thus it can connect to many sources for one task. This concept can bypass the thrrotling of your ISP.

Weaknesses of Xunlei
The speed is extremely unstable. It’s all depend on the task itself. If there are more sources, it would be more stable. How unstable it is? For example, when you have 100kbps for a task, it can sometimes have a sudden drop to 2kbps or lower. Why is this happen? I’m still not sure about this. But, I guess that a task might sometimes experience some file transfer pausing during the process. Thus, the speed might be affected.
