Let’s start with the results for the browsers on my Windows XP SP2 installation, ordered from slowest to fastest. Each test was executed 2 times, clicking on the results will teleport you to the detailed results where you can paste the URL’s of another test to compare.
- msie 6 (6.0.2900.2180.xpsp_sp2_qfe.070227-2300): 47203.0ms +/- 16.7% and 47882.2ms +/- 4.9%
- IE 7 (standalone version, see below): 44726.2ms +/- 4.1% and 42655.2ms +/- 5.0%
- firefox 2 (18.104.22.168): 26025.4ms +/- 4.5% and 25305.0ms +/- 1.1%
- opera 9.27: 14202.0ms +/- 1.0% and 14755.6ms +/- 2.4%
- opera 9.5 (b2, build 9945) produced a number of ‘NaN’s’, but is clearly faster then it’s predecessor
- safari 3.1 (build 525.13): 6759.0ms +/- 1.2% and 6750.8ms +/- 2.0%
- firefox 3 (rc1): 5830.4ms +/- 2.2% and 5765.8ms +/- 1.0%
The MSIE7-results are probably not entirely representative, as I use Tredosoft’s standalone IE7. This is a bit of a hack to have IE7 on my otherwise MSIE6-based system. Moreover my corporate Windows-installation is infested with crapware, notably McAfee OAS and Zonealarm seem to be slowing things down enormously. The codinghorror-tests indeed show significantly better results for this browser, although IE does have serious issues with string concatenation, which should be fixed in IE8.
- opera 9.27: 15343.2ms +/- 1.1% and 15499.4ms +/- 1.1%
- firefox 3 (rc1, official mozilla build): 5352.6ms +/- 1.1% and 5343.8ms +/- 0.6%
- firefox 3 (b5, included in ubuntu 8.04): 5195.2ms +/- 1.6% and 5240.2ms +/- 1.4%
- konqueror 4: not tested yet,
results will follow later todaycan’t get test to completely run, any KDE-user want to give this a try?
Firefox 3 RC1 seems slightly slower then b5, but maybe the Ubuntu-b5-version is compiled with optimizations? Firefox is also faster on Ubuntu, but the anti-virus-bloat is probably messing with our heads here (although Opera is slower on Linux, go figure).
