Does tixati uses more data than normal torrent programs?

Define data.

More RAM consumption? Last time I checked against qbittorrent, Tixati was actually way more lightweight, same torrents on both clients.
More CPU usage? No complains from this side, some spikes when downloading huge files at high speeds.

Oh and take some time to define what a "normal torrent program" is.

The media would say data (celphone term) = data throughput used, 'normal torrent client' most likely for a outsider/random person to have heard of = utorrent (sadly)
