Of both clients, the settings are the same:
- Port 21
- Protocol: FTP + TLS Explicit Encryption (I also tried implicit and SSL)
I confirm that both clients switch to a secure channel via the AUTH TLS and PROT P commands.
However, WinSCP transfer rate to upload the same file is about 3 or 4 times slower than FileZilla. I did multiple tries, also tested implicit, explicit, passive, active... but same result. I also tried the winscp.com command-line version (which is what I really need), with same results.
Is there anything I'm missing?
Thank your very much!
