I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Load Disqus comments only on demand if you give a shit about page weight and your visitors. Even with no comments, i.e. an empty comment form, calling Disqus will load an extra 226Kb. If your page has comments this can be far higher. This Gist accompanies my blog post: http://internet-inspired.com/wrote/load-disqus-on-demand/
// Requires jQuery of course.
$(document).ready(function() {
$('.show-comments').on('click', function(){
var disqus_shortname = 'YOUR-DISQUS-USERNAME'; // Replace this value with *your* username.
// ajax request to load the disqus javascript
$.ajax({
type: "GET",
url: "http://" + disqus_shortname + ".disqus.com/embed.js",
