To achieve usable performance, every major runtime has resorted to non-standard internal optimizations for Web streams. Node.js, Deno, Bun, and Cloudflare Workers have all developed their own workarounds. This is particularly true for streams wired up to system-level I/O, where much of the machinery is non-observable and can be short-circuited.
For example, a 500km route might be broken down into ~100 such shortcuts. If each A* shortcut calculation explores 100-1000 detailed road segments, the total detailed segments visited by A* might be around 10,000-50,000. Compare this to the 1,000,000+ segments the old A* might have needed for the entire route!
