Batch Script WinSCP.com Parallel Transfer (mget all files in folder)

Hi,

I am currently developing batch script for my download speed test. My internet subscription is 300Mbps, however when I try to
the file being transferred in a queue one by one. I suppose this is single thread FTP transfer and the throughput I'm getting was less than 300Mbps (around 150Mbps).

However when I am running 3 simultaneously winscp.com (ftp client), the throughput able to reach 300Mbps.

Is there any winscp.com command for parallel (simultaneously get files) or multi thread transfer on CLI (cmd)?

Thank you.

WinSCP scripting does not support parallel transfers.
Though, see:
