Cyberduck v9.4.1 Multiple Connections Question

[WhatImListnTo]

I have version 9.4.1 installed under Windows 11 Professional. Under Edit|Preferences|General|Transfers I have Transfer files: Open multiple connections selected. In the Transfers window, I have Unlimited bandwidth and 5 Connections set. I am only seeing Cyberduck establish a maximum of two connections for all SFTP transfers though. Only one of these two connections is actually used for data transfer.

My question: does Cyberduck have the ability to perform simultaneous transfers using multiple connections? I am transferring from my local drive to an SFTP server, and I see only a single SFTP connection used for all data transfers.

My expectation-- I set 5 connections within options, so five files will be transferred simultaneously with Cyberduck having no limit on used bandwidth. This does not appear to be happening.

Also, I found this thread related to my question below:

I am unable to get the above to work. When I transfer over 100 files, all file transfers are one at a time using a single SFTP connection during usage even though I have my settings configured per original post.
