Well, I now i'm nagging a lot, but i think if i keep on posting someone might bennifit from this exprience.

I just downloaded Ares, and it was FAST at least for some files it even reached 30 kb/s that's more than 10 times faster than what I had in limewire, the only drawback was that it reliable on very popular files, otherwise it doesn't act that good.

I tried port forwarding as lilthugz suggested, didn't do much although it was a good idea.

And what's weirder is that limewire tells me for example that I have 7 hosts downloading from, yet the speed doesn't exceed 2kb/s (sometimes even 0kb/s!!!)

So I think these are my options,

1- The ISP is messing with me and it's doing what it can to limit p2p, and it did discover limewire so it cut its speed and once it finds about the other p2ps it will do the same.
2- Something's wrong with Limewire
3- I have some sort of firewall I don't know about (because when I downloaded Ares it said that it detected a firewall-strange-I was sure no firewall existed)
4- Something other thing is wrong with my computer
5-Something else I have not taken into account.

ye God, this is a problem for the ages!!
