Listing directory contents very slow (45 seconds to over a minute)

[cyberduck]

43dce55 created the issue

When attempting to list a directory from the FileApp Pro ftp server on the iPhone, it takes a really long time (>45 seconds). The directories only have 2-9 items in them.

If I let it run 1-2 seconds and hit the STOP button, the listing come back complete.

If I don't hit the stop button, it takes 45 seconds to a minute or longer to return the directory listing back-- even with only two items in the directory.

If I use FileZilla 3.5.2 and connect to the same iPhone via FileApp Pro, the directory listings are returned almost immediately (<2 seconds).

The behavior is correct with FileZilla 3.5.2

I observe this behavior as well, running 4.2.1 (9350) on Windows 7 x64.

Nothing wrong in the transcript. I have no explanation if the listing is slow.
