SSH has a much higher overhead than FTP or HTTP. That said, you can try
different ciphers (arcfour or blowfish-cbc are usually fastest),
enabling/disabling compression (depending on your relative quantities of
bandwidth and CPU either could be faster) or bumping the sftp buffer
size (the sftp -B option).
If it takes a while to log in (I'm not sure what you're counting toward
your throughput figures) there's a few possible causes:
