How fast is the connection? What throughput do you get? How long does it take? How fast are the discs involved? Which OS? Any systems in the network path that could slow down transfer?

We want to know if there are VPN tunnels or any other constriction points between the host you send from and the host that reveives.

Otherwise - compress the file first, then send it, decompress on the other side.
Code:
gzip -9 bigfile
sftp myname@remotenode << EOF
put bigfile.gz
exit
ssh myname@remotenode "gunzip bigfile.gz"
