Large File Transfers

So I’m working on a project where I need to send large files(1-100 mb) to other users over a network with a reasonable speed (a few seconds). I’ve been working with the LLAPI but haven’t been able to get anywhere close enough to the necessary efficiency. I’m wondering if there is a better approach using native Unity tools that I might not be aware of or external tools. Thanks in advance.

I would recommend just a third party FTP library. You’ll need to figure out how to manage the client-server infrastructure, but that protocol was designed for this, and there are a bunch of open source solutions available online.
