This echoes my thoughts exactly. Right now, we're actually more limited by the JS UI so a couple 100 MBs is the most you can do in a browser otherwise the UI becomes really slow. There's a lot of room for improvement - we're using React and that's causing a bunch of un-needed re-renders right now that we don't need. We probably need to create our own DAG based task management system and use Canvas to render everything - with all that, workflows on much larger files will hopefully become usable.

You can now use the file api to work with terabyte sized files if your disk can handle it.

Browser is pretty powerful nowadays.
