after you asked i checked again and here's the result

Wow, that is strange internets you have there, because you previously said:
my upload speed is 424.9
kilobit/s
Now your new upload speed is 234 kbit/s. So that means your throttle should be set much lower, about 20 outgoing.
But your connection seems very bad, so you should maybe try 5 outgoing, and see how that works. That is probably what utorrent is automatically doing, since they use delay-based throttling which will choke off uploading to nothing on a really slow connection.
Also maybe try setting incoming to 50, outgoing to 10, auto-limit off. See how that works. Then try slowly adjusting each one, see what the effects are.
My experience is that Tixati has always been faster than the other clients on my various connections, so I don't know what problem you have. But even if you are a bit slower (and I have my doubts about that) it isn't worth using that pile of junk that is utorrent. There are other clients but maaaaaaaaaaaan that one is the WORST of them all.
