body: <p>so what happening to me is when i open 1 puppeteer instance it would go fast a but the more i open the more time it need to load the URL + fill information is that a normal thing ?</p>
  <pre><code>const puppeteer = require('puppeteer');
  
  (async () =&gt; {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto('https://example.com');
    await page.screenshot({ path: 'example.png' });
  
    await browser.close();
  })();
  </code></pre>
