4k plex streaming, how to buffer further ahead?

[calisro (Rob)]

The newest beta has multithread download support under certain circumstances. I've not tested it but perhaps you could see if it helps.

Multi threaded downloads - comments and testers needed

This will work for anything which calls the internal operations.Copy function. This is sync/copy/move and friends copyto/moveto. If you are using rclone mount with --vfs-cache-mode full it will be active. It won’t be active for rclone serve though, but if you are using rclone serve http then you could use rclone to do multithreaded downloads from it.

You would need vfs in full mode though. I'm not sure how it works through the cache backend either.
