It downloads the next couple parts in parallel using > range requests, and then buffers them in memory in order to reorder them and > expose a single contiguous stream. I translated the logic to Java and > modified the S3AFileSystem to do similar things, and am able to achieve > 150MB/s download speeds as well.
