Зачем верить? Что мешает самому сделать такой тест? :)

1) Bun

let n = 0;
const server = Bun.serve({
  port: 8008,
  fetch(req) {
    n++;
    if (n % 10000 === 0) {
        console.log(n);
    }
    return new Response("Bun!");
  },
});
console.log(`Listening on http://localhost:${server.port} ...`);

let n = 0;
const server = http.createServer((req, res) => {
  n++;
  if (n % 10000 === 0) {
    console.log(n);
  }
  res.end('Node!');
});
server.listen(8008, () => {
  console.log(`Server running at port 8008`);
});
