Go v1.15.8 vs Node v14.15.5 Microbenchmark

This is my fourth 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 v14.15.5

Takeaway

Go is 2.26x as fast as Node.js for this particular benchmark. Node.js is relatively slightly faster this time, as the last time I ran this benchmark Go was 2.69x as fast as Node.js.
