sftp(1) file transfer pipelining patch under development

A new patch for OpenSSH is under development, which will improve dramatically the performance of a large number of small file transfers, over high bandwidth high latency links, like the now pervasive wireless networks in sftp(1).
The algorithm pipelines readdir/open/read/write calls with a small window for file handles and avoid unnecessary round trip delays.
This improved file transfer mechanism which is possible due to the flexibility of the SSH+SFTPv3 protocols, will allow administrators to securely transfer large quantities of small files in a much shorter time frame using sftp(1).
New regression tests are also being written to make sure this functionality will be 100% reliable and tested, in the current release and all future OpenSSH releases!
Thanks.
