parse5 is about half the performance of htmlparser2

See original GitHub issue

I’m running a benchmark that parses MDN and GitHub using _useHtmlParser2 true and false and I’m getting considerably faster times using htmlParser2.

Is there ongoing work you need help with this? I don’t feel great passing _useHtml5Parser: true

The benchmark is literally loading MDN and all (html) subresources or a GitHub issue and all (html) subresources with Cheerio.

How do I work on this?

Thanks for the great library!

I’m working on JS bindings for https://github.com/cloudflare/lol-html at the moment. Which provides low output latency spec-compliant tokenisation along with CSS-selectors support, but orders of magnitude faster than parse5. Maybe it will be useful for your case.

Hey, both ended up being too slow for my particular need so I ended up parsing myself https://github.com/testimio/mhtml-parser because I only needed very primitive processing and structure rather than creating a whole dom tree.

I used _useHtmlParser2: true in my cheerio code at https://github.com/testimio/mhtml-parser/blob/master/src/link-replacer.js#L87 and I still use cheerio for svgs 😃
