# 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.
It uses an implementation of the [Leibniz formula for π](https://en.wikipedia.org/wiki/Leibniz_formula_for_%CF%80) to do the comparison.
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.
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:
## 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 +
```
### 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.
