Browser Performance/Capability Benchmark Testing

In the past few years the browser wars have heated up again. Performance and capabilities of some browsers varies greatly. There are several standard tests that are publicly available to benchmark your systems. WebKit (Safari, Chrome & Chromium) and Mozilla (Firefox) based browsers, as well as Opera perform pretty well, MSIE is currently trailing in most cases.

Here are a few common ones…

Browser capabilities comparison testing

Browsers tend to evolve quickly, but they often do not offer the same capabilities cross-platform. As a result of this, there are many standard tests available to the developers of browser software to test for compliance with modern web standards.

Before making use of a specific capability in your web application, it’s often best to determine which browsers can support it.

Sniff for SSL capability of browser

If you run a secure server, you often have some non-secure content prior to authentication of a secure session. To provide a mechanism to show a page prior to authentication, you can “sniff” for the clients capability with a small bit of JavaScript.

First establish a global variable on the page:
<script type="text/javascript">
var sslok = 0;

Then, include a JavaScript file that is ONLY available via a secure
<script type="text/javascript" src=""></script>

The ‘sniff.js’ file should contain (at a minimum):
sslok = 1;

Finally, check and act on the value:
<script type="text/javascript">
if (sslok === 1) {
window.location.href = '';
