Will requiring module in microjob harm performance?

[wong2]

(async () => {
  const { start, job } = require("microjob");

  try {
    // start worker pool
    await start();

    // this function will be executed in another thread
    const res = await job(async () => {
      const module = require('some-module')
      return module.someFunction()
    });

    console.log(res);
  } catch (err) {
    console.error(err);
  }
})();

I'd like to know will the require in the job make the performance really bad?

It dependes but generally no. require is a kind of readFileSync operation so it takes the time of reading a file synchronously.
