Is deluge a disk fragmentation cause ?

[pumy]

Hy everybody.
I'm using Deluge 0.5.9.1 64bit and i recently discover that deluge write to the disk as fast as it download (using iotop http://packages.debian.org/sid/main/iotop). But the problem is that, on a 2796 piece torrent (only one file), deluge wrote 20469 extends on my EXT3 partition (on ubuntu use "sudo filefrag path_to_your_file" to know the number of extends).
I don't really know if deluge is responsible, but it occur only on files I've downloaded with deluge.
Please confirm... (I'm sorry for my bad english)
