# Primes Benchmark

This is benchmark, inspired by [Google IO](http://www.youtube.com/watch?v=UJPdhx5zTaw) talk on V8 performance.

## Requirements:
`sudo apt-get install make g++ nodejs npm openjdk-7-jdk ruby python`

## Benchmark:
`make`

## Results:
```bash
$ make bench PRIMES=50
c++ x 218 ops/sec ±4.74% (76 runs sampled)
java x 3.85 ops/sec ±8.92% (25 runs sampled)
v8 x 54.04 ops/sec ±0.84% (86 runs sampled)
ruby x 31.18 ops/sec ±0.77% (76 runs sampled)
python x 45.37 ops/sec ±0.84% (74 runs sampled)
```

```bash
$ make bench PRIMES=500
