Seeing TCP Congestion Control — CUBIC, BBRv3, and a gVisor Netstack Running in Your Browser
On July 28, 2026, "Simulating TCP loss and congestion in browser using Go/WASM" went up on Hacker News. It builds two entire copies of the gVisor netstack to WebAssembly, runs them in browser workers, and puts a bottlene
