There are no spyware. The thing is only about 300kb, and I spend hours decompiling the whole thing, trying to figure out exactly what it does. Not a smart thing to do. What a waste of time...
Basically, it just changes MTU value and enlarges acknoledgement windows. It should help on my 5M downstream cable connection, especially when nearly all the bandwidth is saturated. But it doesn't.
BT download depends on other users, but there should be at least a little bit of difference.
I knew so little about networking. Out of my league on this... Can anyone help?
