The code performs a recursive fibonacci to the 47th position with the result of 2,971,215,073.

Fibonacci can be written many different ways. The goal of this project is to compare how each language handles the exact same code.

Here is the Ruby version:

def fib(n)
  return n if n <= 1
  fib(n - 1) + fib(n - 2)
end

puts fib(47)

Here is the Crystal version:

def fib(n)
  return n if n <= 1
  fib(n - 1) + fib(n - 2)
end

puts fib(47_u64)

Too keep a level playing field, only common "release" flags are used in the compilation step. This allows for compiler optimizations like inlining and constant propogation but removes anything considered dangerous i.e. bypassing out of bounds checks.

All tests are run on:

AWS EC2 - m5.large 2 vCPU
Processor: Intel Xeon 3.1Ghz
Memory: 8 GiB
OS: Ubuntu 20.04
Docker Base Image: ubuntu:20.04

How to run them

You can run the tests using Docker: docker run -it drujensen/fib

By default, it will compile and run all languages 5 times. Totals are calculated by adding the average compile and run times.

To only run a subset of the languages, provide a list of extensions and optionally the count:

docker run -it drujensen/fib ./run.sh s,c,cpp,go,rs,swift 5

To run in the background using nohup:

nohup docker run drujensen/fib:latest > results.txt 2>&1 &
