Asynchronous Google Analytics snippets (v10)

Revision 10 of this benchmark created on

Description

Test case which measures the speed difference between the default asynchronous Google Analytics snippet and the optimized version.

Note that I commented out the s.parentNode.insertBefore(g, s); line in both scripts, since otherwise the <script> element gets inserted a few thousand times every time you run the tests. Since this code is the same in both scripts, it shouldn’t have an influence on the results.

Test runner

Ready to run.

Default snippet
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXX-X']);
_gaq.push(['_trackPageview']);
(function() {
 var ga = document.createElement('script');
 ga.type = 'text/javascript';
 ga.async = true;
 ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
 var s = document.getElementsByTagName('script')[0];
 // s.parentNode.insertBefore(ga, s);
})();
ready
Optimized snippet
var _gaq = [
 ['_setAccount', 'UA-XXXXX-X'],
 ['_trackPageview']
];
(function(d, t) {
 var g = d.createElement(t),
     s = d.getElementsByTagName(t)[0];
 g.async = 1;
 g.src = '//www.google-analytics.com/ga.js';
 // s.parentNode.insertBefore(g, s);
