Major Description
The processor PutSFTP is based on PutFileTransfer.
Before an actual upload takes place, potential conflicts (e.g. existing file) are identified and resolved using identifyAndResolveConflictFile(...).
As part of this process, information on the target file is retrieved using FileTransfer.getRemoteFileInfo(...).
In case of PutSFTP this is implemented by SFTPTransfer.
The implementation of getRemoteFileInfo executes ls on the target directory path. In case there are a lot of files inside the remote directory, e.g. >10.000 files, the listing reduces the performance of PutSFTP significantly.
Instead of a listing on the directory, file information should be retrieved using either ls or stat on the target file directly.
