Slow enumeration of files on mapped network drive

[ThatDeadDude]

FileZilla Client becomes extremely slow to enumerate local files when the local site is on a slow network drive. In this particular case the physical "local" drive is at a remote location such that network latency is quite high.

Windows Explorer is able to enumerate files and folders on this drive much faster than the FileZilla client is, so my guess would be that the API calls being used are inefficient in this situation.

For example, if I navigate to a new folder it might take 2 seconds for each child item to appear in the local site pane, and FileZilla is unresponsive until all items have been populated. If I navigate to the same folder in Windows Explorer it might take 2 seconds total for all items to be populated.
