@moeller0 is there any sense in which those spikes we see could be smoothed by - yes, call me crazy - actually introducing delay to reduce jitter? Or is this a stupid idea? It's not that the game could be compensating for latency and/or jitter in a broken way that might be fixed by actually introducing delay?
Also do you suppose that burst in the first half is a game update or something? And presumably unrelated to the problems?
And yes, such a connection looks ace compared to my 4G connection, but would have given me significantly less motivation to mess about with cake-autorate!
