10 things I learned making the fastest JS server runtime in the world
summary
Claims a custom runtime called es4x project combines grouchy s (a JVM JIT) with Vertex I/O and ES modules, removes Node native bindings and runs on the JDK. Results show big wins: JSON serialization jumps from ~550k to >1,000k RPS, Postgres single-query goes from ~11k to ~67k (≈6x), and concurrent DB workload reaches ~42,900 RPS, putting a JavaScript framework into the benchmark top‑10, so the build actually works.
