Excellent source; thanks!

It’s probably worth clarifying that Node is ⅓ the speed of Java in some of these cases and that the Node implementations use both fixed size typed arrays as well as worker threads, features that aren’t common practice in most Node programs.

I wanted to illustrate the fairly "wide dynamic range" available. A lot of typed, GCed languages require significant effort to write highly optimized code anyway, and the optimized code rarely looks like the idiomatic one.

But even with idiomatic code the performance is quite good - the JITs are very high quality.

I didn't downvote you – in fact, I upvoted you. But I should also make the point that worker threads do not support importing native Node modules that were built directly on the V8 API. For example, most popular sqlite libraries (better-sqlite3, sqlite3) are not usable with worker threads.

I'm mulling contributing N-API support to the libraries... but I haven't even done any research or planning work yet.
