Just curious: Why does searching/downloading work so much better in Xolox than it does in Limewire?

I can do the same search in both programs after about 30 minutes of sitting on the network. Limewire finds the file twice, Xolox finds it 50 times.

If I disconnect from whatever crappy ultrapeer I happen to have hooked into then I can maybe find it 5 times, or maybe not find it at all - or maybe if I am extremely lucky I can find it say 10 times.. When I try to download the file though, it only gets the file from one or two places - and the transfer generally takes so long that one or two of the hosts go offline and it's just a waste of time. Xolox seems to get the file from as many places as it possibly can - resulting in transfers of 200K/second sometimes. Why can't limewire do this?

The ultrapeers seem to be the real downfall of Limewire - since they were introduced the program has become pretty much useless.

I'm not complaining.. I am grateful for any free software I can get.. I am just wondering WHY...?

It has been said that it should get better once everyone is using the new version that supports the new features, but all I can connect to now are ultrapeers - which leads me to believe that people are indeed using the new version, and things are still sucking..
