Playing with counting word frequencies (and the performance thereof) in various languages. See the full article for context and background: https://benhoyt.com/writings/count-words/
To run the tests and benchmarks (you'll need Go, Rust, Python 3, AWK and perhaps other tools installed). Only tested on Linux:
./test.sh
./benchmark.pyFor the latest results (run on my machine against these versions), see the article's performance results section.
