[JSch-users] Transferring large number of small files

Hi all.

I'm trying to transfer a large number of small files to a remote server (with reasonable latency) using JSch.

The code I'm using creates a Session and a ChannelSftp and then iterates over the local files (some times thousands) to transfer them to the server, with something like (I omitted exception handling for simplicity):

	Session session = ...;
	ChannelSftp sftp = (ChannelSftp) session.openChannel("sftp");
	for(Path path : ...){
	    sftp.put(path.toString(), String.format("/destination/%s",path.getFileName().toString()));
	}
	sftp.disconnect();
	session.disconnect();

The problem is this is very slow (sometimes it takes hours) compared with the something like:

	rsync -av /local/<some glob> server:/destination/ # takes seconds

Is there any faster way to transfer large number of small files with JSch?
