How We Ran Our Tests
The browsers we tested are:
- Google Chrome 18.104.22.168 (Stable)
- Google Chrome 2.0.164 Beta (Developer Preview)
- Mozilla Firefox 3.0.6
- Mozilla Firefox 3.1 beta 2
- Opera 9.63
- Apple Safari 4 beta 528.16
- Microsoft Internet Explorer 7: IE7.0.6001 (tests were run on Windows Vista, same Hardware)
- Microsoft Internet Explorer 8: IE8.0.7000 Beta (Windows 7 Public Beta)
Results 1: DOM Manipulation Performance
The fastest browser is Safari 2 Beta with Chrome as a close second. Firefox 3.1 Beta 2 is better than FF 3.0.6, but still 60% slower than the fastest. Both Internet Explorer versions are way too slow, with IE7 taking 7 times as long as Chrome to perform our complete test parcour. On IE7 some tests took 35 times longer than on Chrome.
Results 2: AJAX Performance
The second set of tests performs a number of HTTP calls to the PRTG webserver and inserts the results into the page (e.g. loading a tab, refreshing data).
In this case Firefox 3.1 Beta, Safari and Chrome are more or less equal in performance. The Firefox upgrade from V3.0 to V3.1 boosts performance considerably. Both IEs are very slow, up to 8 times slower than Chrome.
Currently our clear browser-of-choice for PRTG is Chrome. It is as fast as Safari 4 and runs PRTG more reliably (we have seen installations of Safari that did not show PRTG's context menus from time to time). Firefox 3.1 is the second best choice. IE7 and IE8 are way too slow.
