Speed of network copy

I needed to copy some big video files from my NSLU2 NAS box to my desktop a couple of days ago and noticed that, using Konqueror, the FTP protocol was significantly faster than using SMB. * Using ftp://192.168.n.n/DISK 2/video/… gave me around 5.5MB/s * Using smb://192.168.n.n/DISK 2/video/… gave me around 3.5MB/s Of course, the NSLU2 is constrained mainly by only having a 10M network interface but this is a very significant difference in speed.
