Re: Download speed
SSH (SCP) will be always slower than FTP, because of the encryption. Current implementation of SFTP in WinSCP is rather slow, I have just finished new version, which should be times faster. I'll release it soon.

Bug reports without an attached log file are usually useless.
Have you selected SCP or SFTP on login dialog?
