Transfer huge amounts of data (fastest way on secured connection)

Hi,

what is the fastest way to transfer huge amounts of data on SAP PO?

I have no doubt that FTP is faster but I am checking on these ones

SFTP

HTTPS
FTPS

I can't see any comparison of all three protocols with regards to the speed of transfer?

We are dealing 100k+ of files with around 200kb file size to be sent on a regular basis to our 3rd party partners and would like to know what is the best approach that we could take.

Thank you.
