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!
