A lot of developers, especially ones who haven&#39;t used Node.js in production, seem to believe that Node.js is faster than other interpreted languages such as PHP, Python, and Ruby.
These claims include:
<ul>
<li>Node.js/V8 is x times faster than y language.</li>
<li>The JavaScript reactor pattern will always handle concurrency better than any multi-threaded application.</li>
</ul>
I can certainly believe the first claim, yet I am unable to find any satisfactory benchmarks showing this. The second claim seems unfounded, or at least too absolute.
What are the characteristics of Node.JS and V8 that justify such claims?

A lot of developers, especially ones who haven't used Node.js in production, seem to believe that Node.js is faster than other interpreted languages such as PHP, Python, and Ruby.

These claims include:

- Node.js/V8 is **x** times faster than **y** language.
- The JavaScript reactor pattern will always handle concurrency better than any multi-threaded application.

Where is the evidence for the performance of Node.js?
