I'm not convinced. (A bit of advice: if you wish to make a statement about performance, always start by measuring things. Then when somebody asks you for proof/data, you would already have it.) If what you're saying were true, it would be a big deal, except unfortunately it isn't.

Dispatch has overheads, but it's largely insignificant. Where it otherwise would be significant:

1. Fused kernels exist

2. CUDA graphs (and other forms of work-submission pipelining) exist

Turns out how? Where are the numbers?

What's this obsession with SQLite? For all intents and purposes, what they'd accomplished is effectively a Type 2 table with extra steps. CRDT is totally overkill in this situation. You can implement this in Postgres easily with very little changes to your access patterns... DISTINCT ON. Maybe this kind of "solution" is impressive for Rust programmers, I'm not sure what's the deal exactly, but all it tells me is Fly ought to hire actual networking professionals, maybe even compute-in-network guys with FPGA experience like everyone else, and develop their own routers that way—if only to learn more about networking.

I respect Fly, and it does sound like a nice place to work, but honestly, you're onto something. You would expect ostensibly Public Cloud provider to have a more solid grasp on networking. Instead, we're discovering how they're learning about things like OSPF!

Makes you think that's all.
