Been testing and comparing both tuotu beta 3 and thunder...
Tuotu3
Speed - Average 50-170
Drawbacks - Buggy and laggy
Comment - Can be fast, but i hate it when i need to turn it off everytime i wanna play games... even offline games

Thunder
Speed - 20-190 (Tested it today only so result may vary)
Drawbacks - Where is the source page to display the peer connection? Is there none or wat.. cant really find it so i have no idea am i dling it from local peers or international peers and hey... the idea of promoting to different level status to get more dl speed and source base on the amount u dl and seed just seem lame to me compare to tuotu. Seem to use more mem usage - 90mb ram for dling 2 torrent.
comment - Need to test it more since my time of use is only 1 day compare to tuotu which been using for more than 6 months

Would glad to hear more comments from those experience xunlei user especially for those with high 'level'

Heres a ss of xunlei...

I'm using default language pack Chinese PRC which can be install from control panel - Regional and Language Option - Advance

Or 'Microsoft Applocale' which is capable of translating languages like chinese, japanese etc
