Is Cheerio faster than Puppeteer?

Cheerio is much faster than Puppeteer. This is because Cheerio is just a DOM parser and helps us traverse raw HTML and XML data. It does not execute any Javascript on the page. On the other hand, Puppeteer runs a full browser and executes all the Javascript, and processes all XHR requests.

You won't be able to observe the speed difference in small projects but it compounds on large projects and becomes very apparent.
