just to do some napkin maths, the entire constellation is supposed to be 12k satellites. Some googling gives 20Gbps throughput per satellite, so that'd be about 240k Gbps per second. Now of course the satellites keep exchanging information themselves and not all satellites are everywhere all the time but ignoring that, and let's say you can assume ten times as much bandwidth because not everyone is online at the same…

Gigabit speeds are great, but 80% of the value of Starlink is just getting the 11 Mbps to the people who can't get even that speed in any better way. There are many (millions?) of Americans who don't have that. So let's calculate from that number (or 10 Mbps, to make it easy). 240K Gbps * 1000Gb/Mb / 10Mbps/customer = 24M customers. I've heard that in most residential cases, people on average use about a tenth of the…

You are arguing against exactly what Elon had said at launch. I'm not being unfair with a beta. I've lived this industry for a while; latency will go up with congestion. Let's revisit this comment in a year.

Which statements of his am I arguing against? Also if buffers are configured to be very small then congestion does not have to add more than a fraction of a millisecond of latency. Bufferbloat is endemic but it is not unavoidable.

Has anyone come out with a reason for the size? I mean they seem to reuse a lot of the same textures throughout the game so I have a hard time understanding how it managed to swell to that.

IDK if they do this for PC versions... But a lot of these games not only Reuse textures but also duplicate them. They do this to improve load times for levels/etc (less seeking). Playstation DOOM is an early example of this pattern. The WAD files were actually 'per-level' and contained all sprites/textures/etc used in said level.

My understanding is that the FCC is very partial towards existing ISP. If I'm correct, how likely are they to negatively impact starlink accessibility to end user? Do they even have such power? I would very much appreciate if someone more knowledgeable could give her opinion.

Can anyone tell me why this was not previously possible? Both latency and speed? What did Starlink do differently
