One solution I found is using 7-Zip to first split the file in chunks, ideally 9 chunks. If you don't want to compress you can set the compression level to "store", which will split the file super fast. This is also great because 7z has checksum when putting the file back together. Obviously this is only worth it for large files that take some time.

You are transferring a single file only. Did you expect WinSCP to upload chunks of the same file using multiple connections? WinSCP does not support that. WinSCP can only upload different files using parallel connections.

The transfer happens with one download thread even when I have the calculate file size enabled. I think there is something else going on here.

Re: use multiple connections for single transfer not working

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate the session log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

Use multiple connections for single transfer not working

No matter what I try, using multiple connections for a single transfer does not do anything.
I've turned off the "Preserve timestamp" option, checked the box "Use multiple connections for a single transfer", and set the maximum connection limit to 9.
The site I'm transferring files from uses SFTP.
Is this feature currently working with the SFTP protocol? Are there any other settings I should change to get this working?
Thanks,
