Comment 38 for bug 574693

Another workaround which is more Gnome-esque (than Dolphin) is to install thunar, and libdesktop-agnostic-vfs-thunar.

The relevance to this bug is this: perhaps some developer (which I'm not) might want to look over the FTP-related code in libdesktop-agnostic-vfs-thunar, and perhaps use it somehow in Nautilus' corresponding VFS-related code.

Pardon me being a bit off-topic here, but for those who care about the getting fastest file transfer speed on their LAN, and less about tight-security-within-the-LAN, Thunar gave the fastest bulk FTP transfers I've ever seen (connecting to a pure-ftpd server), even 25% faster than doing the exact same bulk FTP copying within Filezilla. My test data was about 5300 files, most are small documents, 1.4 GB, transferred on a gigabit LAN). Compare FTP-within-Thunar to having the same data transferred using SMB (through Nautilus), and SSH/SFTP (through Nautilus) took 134% longer, and 349% longer, respectively. FTP-within-Thunar beat the pants off SMB-within-Nautilus and SFTP-within-Nautilus for speed, when it came to a larger set of small files.

Before flaming me, I feel it's highly relevant to mention these informal stats to underscore the point that in fixing this bug, greatly increased file transfer speed is won (within the LAN, where FTP still has usefulness) for Ubuntu as a whole (as installed by default). Like over twice as fast (even for large collections of tiny files, which usually transfer much more slowly than equivalent amount of larger files), compared to SMB file transfers!
