Interestingly, this crops up in discussions in the Internet.
One discussion seems to indicate that pscp is (was?) strictly
syncronous.

One test might be to check other SCP tools, such as WinSCP or Filezilla.

Other things to check:
- Age of the pscp client ... used to be an OpenSSH bug that slowed things down

pscp rides on the ssh protocol which encrypts traffic. Samba/SMB/CIFS does not have the encryption requirement.
