Go v1.13.3 vs Node v12.12.0 Microbenchmark

Multithreaded JavaScript, O'Reilly 2021, has been published!

This is my third annual microbenchmark comparing a very simple Node.js and Go HTTP service running on the local machine. Usual disclaimer: this benchmark is highly contrived and doesn't resemble real-world usage. If you'd like to view the code for the benchmark visit the original benchmark post.

As per usual we run the benchmark using a tool called siege:

siege -t 2m -b http://localhost:8000/

The results are as follows:

Node v12.12.0

Go is 2.69x as fast as Node.js for this particular benchmark. What's the most interesting to me is that the Node.js results have been the same between v8, v10, and v12. However, Go increased in speed 20% from v1.9 to v1.10, and another 34% from v1.10 to v1.13.
