Cybernetnews compared the performance of seven browsers with the SunSpider JavaScript Benchmark test and found out that the latest builds of Firefox 3 are almost ten times faster than Internet Explorer 7:
I'm sure what most of you care the most about are the facts, and so I've compiled the results of the SunSpider JavaScript Benchmark test for each of the different browsers. All of the tests below were performed on the same Windows machine, and the Firefox 3 nightly builds definitely came out on top. Here are the results sorted from best to worst (each one is hyperlinked to the full stats):
1. Firefox 3 Nightly (PGO Optimized): 7263.8ms
2. Firefox 3 Nightly (02/25/2008 build): 8219.4ms
3. Opera 9.5.9807 Beta: 10824.0ms
4. Firefox 3 Beta 3: 16080.6ms
5. Safari 3.0.4 Beta: 18012.6ms
6. Firefox 2.0.0.12: 29376.4ms
7. Internet Explorer 7: 72375.0ms
It's important to know that every time you run the SunSpider Benchmark it conducts each test five times, and the result is the average of the five tests. So it is a rather thorough test, and definitely shows off the speed improvements that Firefox 3 is going to be bringing to the table.
