The problem is that torrentRow() does linear search over the list of all available torrents. So it doesn't scale well for large number of torrents. Removing the copying of QString from linear search inner loop, speed up it considerably. The proper solution should be using hash table instead of linear search. This require more radical changes in TorrentModel and may be done in a separate commit.
