To check whether you're an ultrapeer, click on LW's Connections tab...you'll see your connection status in the top left corner. Either leaf or ultrapeer.
If you don't see a Connections tab, click on View > Show/Hide > tick 'Connections'.

If you have a fast connection & aren't firewalled, you'll connect as an ultrapeer if the network needs UPs. Connected as an UP, you may see better search results but you may also see fewer uploads.

In LW tools > options > advanced > performance. You can tick 'disable ultrapeer capabilities' > apply > ok...now you won't ever connect as an UP.

Thanks a ton.
