JS web API framework benchmark

Framework x runtime, realistic API workloads. Results folder: full-1

Each server runs as a single process (no cluster). Every scenario: fresh server, 20s measured x 3 run(s), median reported.
Load generators (oha, k6) and Postgres/Redis (Docker) share the machine with the server, so absolute numbers depend on the host. Compare rows with each other, not with other benchmarks.
Database scenarios are usually bounded by Postgres, which narrows the gap between frameworks. CPU-bound scenarios (large-json, bulk, login) show framework and runtime differences most clearly.
Mixed traffic runs at a fixed arrival rate, so throughput is the same for everyone: compare tail latency and dropped iterations instead.

Overall score

Geometric mean of RPS relative to the best combo in each throughput scenario (100 = best everywhere).
