Ya three is good. Never thought that people didn't want the kind of files you share? Download a popular movie and be sure partial file sharing is enabled, you'll be swamped by uploads.
And a query in the monitor doesn't mean you'll send the seracher a search result. In fact you see more searches because 2.8 uses a QRT (query routing table) of 16KB and 4.8 uses QRT of 64KB. When a QRT is more than 50% filled, there are much more false positives and that what you see in 2.8 (more incoming searches), but that doesn't mean you send more search results.
Anyway use the latest, find files that are wanted and happy sharing.
