By the way, if I recall correctly SFTP is a bit weakly defined, and
the name being used to cover various "looks like my old FTP client, but
works over ssh" scenarios, not just

draft-ietf-secsh-filexfer-00.txt, January 2001, work in progress
Maybe the OpenSsh implementation is the defacto standard.
Good points. Other possible reasons for the speed difference:
- the OP does indeed have assymetric network speed. "Upload is taking
quite a bit longer than the download" describes my ADSL connection
- slow CPU on the downlink side. SSH spends a lot of time encrypting
and compressing data, and if you have reasonably fast networking,
CPU can easily become the bottleneck. I guess the sender needs more
CPU than the receiver, so a slow host A might be the bottleneck
A->B, but not B->A.
