I compared Tixati allocation with µTorrent one.
Same torrent (~24 GB nearly all in one file), same NTFS volume (44% full), pre-allocation enabled in µTorrent, "fast allocate" in tixati.
Right after allocation: Tixati - 2957 fragments (sparse flag present), µTorrent - NO fragmentation (and no sparse flag). Fragment count observed via Defraggler.
