Description Damien Miller 2001-12-12 12:40:22 AEDT

The sftp client does a round-trip for each block it send/retrieves from the
server. This kills performance, especially on latent links.

sftp-client.c:do_download and do_upload should be modified to have at least one
outstanding read request at any one time (i.e readahead).

This has been fixed in the CVS tree.  Both upload and downloading in sftp are 
allowed to have multiple outstanding blocks.
