To clarify: that's probably a WebUI problem; in case there are more than 50 files in a torrent, it displays the status of only the first 50 of them in the Files tab. Which is bad. Not only that, but sometimes the status of certain files in a torrent is displayed as incomplete, completely with an incorrect progress percentage, while the torrent itself is downloaded completely. About cpu and memory consumption, well, it's not very bad, not very bad at all. IMHO every one of all other linux torrent clients with an at least somewhat user-friendly interface tends to use much more of both.
