Bad performance

[pedro757]

What version of Elysia is running?

What platform is your computer?

Linux 6.1.132-1-MANJARO x86_64 unknown

What steps can reproduce the bug?

import { faker } from "@faker-js/faker";
import { createAccelerator } from "json-accelerator";

import { Type as t } from "@sinclair/typebox";

function makeData(n) {
  const data = [];
  for (let i = 0; i < n; i++) {
    data.push({
      comprobanteId: faker.number.int({ min: 1000, max: 100000000 }),
      fechaComprobante: faker.string.alpha({ length: 10 }),
      fechaRef: faker.string.alpha({ length: 10 }),
      numeroComprobante: faker.string.ulid(),
      debe: faker.number.int({ min: 1000, max: 100000000 }),
      haber: faker.number.int({ min: 1000, max: 100000000 }),
      saldo: faker.number.int({ min: 1000, max: 100000000 }),
    });
  }
  return data;
}

function perfCheck() {
  const data = makeData(1_000_000);
  const schema = t.Array(
    t.Object({
      comprobanteId: t.Number(),
      fechaComprobante: t.String(),
      fechaRef: t.String(),
      numeroComprobante: t.String(),
      debe: t.Number(),
      haber: t.Number(),
      saldo: t.Number(),
    }),
  );
  const encoder = createAccelerator(schema);

  console.time("json-accelerator");
  encoder(data);
  console.timeEnd("json-accelerator");

  console.time("JSON Stringify");
  JSON.stringify(data);
  console.timeEnd("JSON Stringify");
}

perfCheck();

What is the expected behavior?

I don't know if this library is supposed to run under a specific enviroment to notice real performance improvement, but I was using it and I don't see the numbers that you put in the README, performance is actually much worse than regular JSON.stringify() as you can see

is it a elisiajs specific library ?
was it thought to handle arrays with large amount of data ?

What do you see instead?

Have you try removing the node_modules and bun.lockb and try again yet?
