X-BeenThere: starlink@lists.bufferbloat.net X-Mailman-Version: 2.1.20 Precedence: list List-Id: "Starlink has bufferbloat. Bad." List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 15 Mar 2022 22:09:26 -0000 Hello, From this list I have learned that Starlink is optimized to shine in tests with speedtest.net and similar sites, but that transmission rates drop quickly after about 15 seconds. How do they do that, technically? Is that a result of Bufferbloat? Is that a a specific code in the modem to cheat, like some car manufacturers cheated on emissions tests? Is that something done in the satellites who shift capacity from other users to those users who initiate downloads? Is that done on the backhaul? Thank you Daniel
