Why is node.js so fast?

I recently read an article comparing benchmarks of all available programming languages and frameworks. I was glad to find out that the new PHP 7 would be almost as fast as HHVM, but what caught my eyes even more was node.js, which was said to be on par with Java and C#. I was confused though, Java and C# are compiled languages that use static/strong typing, they are supposed to be magnitudes faster than dynamic languages like php, javascript, python and ruby. Nonetheless, node.js shows that dynamic languages can be very fast. The question is, why? Does anyone know whats the main reason behind node.js being so fast? And why isnt other languages like php, python and ruby learn from node.js in terms of performance benchmark?

Can you link to the article? I’d like to read it :slight_smile:
