Are downloads sequential on IPFS?

If I download a file via ipfs get or by visiting it on my browser, is the download sequential or is it random?

I saw that trickle-dag was good for things like video, audio, progressive / sequential loading here. However, if downloads are sequential on IPFS, then that means trickle-dag is better for absolutely everything since you’ll download it sequentially anyway.

So… Are downloads sequential on IPFS?

Should I specify -t when I’m adding 0.5 GB .zip files?

I don’t believe downloads are sequential. IIRC it’s basically whatever node responds first to your bitswap requests, and what parts of the content the give you. I’m not sure if adding your content via trickledag would change it.
