A very minimal benchmark: casperjs vs beautifulsoup4

minimal benchmark

python version:

from bs4 import BeautifulSoup

import requests

r  = requests.get("http://www.google.fr/search?num=100&q=scrapping")

data = r.text

soup = BeautifulSoup(data)

for link in soup.find_all('a'):
    print(link.get('href'))

casperjs version:

var casper = require('casper').create();
function getLinks() {
    var links = document.querySelectorAll('h3.r a');
    return Array.prototype.map.call(links, function(e) {
        return e.getAttribute('href');
    });
}

casper.start('http://google.fr/search?num=100&query=scrapping', function() {
});

casper.then(function() {
    links = this.evaluate(getLinks);
});

casper.run(function() {
    this.echo(' - ' + links.join('\n - ')).exit();
});


For a round of 100 calls:
time -o {command}

python version : 1.082
casperjs : 1.107
