Previously, each chunk was delivered through a pull promise. Every pull allocated around seven GC objects (the pull promise, its capability, and the reaction handlers from react_to_promise) and none of them did anything useful. The pull algorithm is now a no-op, and FetchedDataReceiver enqueues bytes into the controller as they arrive.
