# Speed comparison of programming languages

This projects tries to compare the speed of different programming languages.
In this project we don't really care about getting a precise calculation of pi. We only want to see how fast are the programming languages doing. <br />
It uses an implementation of the [Leibniz formula for π](https://en.wikipedia.org/wiki/Leibniz_formula_for_%CF%80) to do the comparison. <br />
Here is a video which explains how it works: [Calculating π by hand](https://www.youtube.com/watch?v=HrRMnzANHHs)

You can find the results here: https://niklas-heer.github.io/speed-comparison/

## Disclaimer

I'm no expert in all these languages, so take my results with a grain of salt.<br>
Also the findings just show how good the languages can handle floating point operations, which is only one aspect of a programming language.

You are also welcome to contribute and help me fix my possible horrible code in some languages. :smile:

<!-- TODO: Create a new video for hyperfine and scmeta -->
<!-- ## Adding new languages

## Run it yourself

Everything is run by a Docker container and a bash script which envokes the programs.

To measure the execution time a [python package](https://pypi.python.org/pypi/lauda/1.2.0) is used.

### Requirements
- `Docker`
- [earthly](https://earthly.dev/)

### Run everything
Earthly allows to run everything with a single command:
```bash
earthly --config earthly-config.yml +all
```
This will run all tasks to collect all measurements and then run the analysis.

### Collect data
To collect data for all languages run:
```bash
earthly --config earthly-config.yml +collect-data
```

To collect data for a single languages run:
```bash
earthly --config earthly-config.yml +<replace me with language name>
```

### Analyse results
To generate the combined CSV out of all results use this command:
```bash
earthly --config earthly-config.yml +analysis
```

## FAQ

> Why do you also count reading a file and printing the output?

Because I think this is a more realistic scenario to compare speeds.

> Are the compile times included in the measurements?

No they are not included, because when running the program in the real world this would also be done before.
