Benchmarks

if you want to add a benchmark, you can add examples/*/benchmark.js like this:

// examples/ssr-normal/benchmark.js
module.exports = (suite) => {
  // add tests
  suite
    // your logic
    .add('ssr#normal /', )
    // your logic
    .add('ssr#normal#stream /');
};

and run yarn benchmark to see the result:

$ node scripts/benchmarks.js
☐  pending   building .../examples/ssr-normal
☒  complete  success build .../examples/ssr-normal
