hello @mzingy wlecome to the forum.

I don’t think somebody has experience with such very special use case you have. you didn’t describe the setup good enough so we can only guess how it works.

IMO it’s not possible to “split” one https request into multiple streams running through different lines - each transaction will always run only through a single line. If there are multiple active connections LB could distribute connections over different lines. With this in mind I could imagine multiple clients syncing lot of small files could utilize more bandwith rather one client transferring big files… I have no idea how wetransfer works maybe they send files in chunks as multiple streams… but this definitely not “normal” for web communications.
