Fibonacci Benchmark

fib-benchmark.asciidoc

Lua v/s JavaScript

Based on lua benchmarks, I conducted my own tests.

Table 1. Benchmark Result

Program	time
fib.go	0m0.068s
fib.c	0m0.076s
fib.js	0m0.180s
fib.lua	0m1.372s

Commands

time node  fib.js

time lua   fib.lua

go build fib.go
time ./fib

gcc fib.c -o fibc
time ./fibc

fib.c

#include<stdio.h>

int fib(int n) {
   return (n < 2)? n: (fib(n - 2) + fib(n - 1)); 
}
int main() {
  printf("%d\n",fib(35));
}

fib.go

package main

import "fmt"

func fib(n int) int {
  if n < 2 {return n }
  return fib(n - 2) + fib(n - 1)
}

func main() {
	fmt.Println(fib(35))
}

fib.js

function fib(n) {
    if (n < 2) return n;
    return fib(n - 2) + fib(n - 1);
}

console.log(fib(35));

fib.lua

local function fib(n)
    if n < 2 then return n end
    return fib(n - 2) + fib(n - 1)
end

print(fib(35))
