Optimize performance

Description

I think we should improve performance. Config like this:

import { defineConfig } from 'orval';
import { execSync } from 'child_process';

const header = ({ title, description, version }) => [
  'Generated by orval 🍺',
  'Do not edit manually.',
  ...(title ? [title] : []),
  ...(description ? [description] : []),
  ...(version ? [`OpenAPI spec version: ${version}`] : []),
];

export default defineConfig({
  main: {
    input: 'https://.../schema/openapi.json',
    output: {
      schemas: 'projects/api/src/lib/main/schemas',
      target: 'projects/api/src/lib/main/target',
      client: 'angular-query',
      httpClient: 'angular',
      mode: 'tags',
      clean: true,
      override: {
        header,
        useTypeOverInterfaces: false,
      },
    },
    hooks: {
      afterAllFilesWrite: (paths) => {
        console.log('Running lint fix and patching generated files...');
        execSync(`bun scripts/fix-orval-params.ts ${paths.join(' ')}`);
        execSync(`bun run prettier --write ${paths.join(' ')}`);
        execSync(`bun run eslint --fix ${paths.join(' ')}`);
      },
    },
  },
  allauth1: {
    input: 'https://.../api/openapi.json',
    output: {
      schemas: 'projects/api/src/lib/allauth1/schemas',
      target: 'projects/api/src/lib/allauth1/target',
      client: 'angular-query',
      httpClient: 'angular',
      mode: 'tags',
      clean: true,
      override: {
        header,
        useTypeOverInterfaces: false,
      },
    },
    hooks: {
      afterAllFilesWrite: (paths) => {
        console.log('Running lint fix and patching generated files...');
        execSync(`bun scripts/fix-orval-params.ts ${paths.join(' ')}`);
        execSync(`bun run prettier --write ${paths.join(' ')}`);
        execSync(`bun run eslint --fix ${paths.join(' ')}`);
      },
    },
  },
  allauth2: {
    input: 'https://.../api/v2/openapi.json',
    output: {
      schemas: 'projects/api/src/lib/allauth2/schemas',
      target: 'projects/api/src/lib/allauth2/target',
      client: 'angular-query',
      httpClient: 'angular',
      mode: 'tags',
      clean: true,
      override: {
        header,
        useTypeOverInterfaces: false,
      },
    },
    hooks: {
      afterAllFilesWrite: (paths) => {
        console.log('Running lint fix and patching generated files...');
        execSync(`bun scripts/fix-orval-params.ts ${paths.join(' ')}`);
        execSync(`bun run prettier --write ${paths.join(' ')}`);
        execSync(`bun run eslint --fix ${paths.join(' ')}`);
      },
    },
  },
});

usually takes omething like 20 seconds. I expect something like 500ms in those cases. Shemas are not that big to take so much time ...

I double checked it with ai and there is a slow part in codegen ...

Current behavior

Generation usually takes around 20 seconds which seems to me too much. My schemas are not that large...

Proposed behavior

I expect time in milliseconds not in seconds ...

Proposed solution

Focus on bottlenecks in the codebase asn measure it and add performance becnhmarks in readme etc...
