It's about downloading torrent from the swarm using magnet link. From what I saw, if a peer who sent some meta data disconnects, Tixati forget data downloaded from that peer and starts all over again. Sometimes I wait for the meta data for minutes, watching several disconnected peers, who sent almost complete meta data. I don't know if it's possible, but it would really help if downloaded meta data was remembered after peer who provided it disconnects, to speed up the process.

I have noticed the same and agree. That said if it takes a long time to get the meta it will take forever to download. Is it worth having.
