TimePedia did a benchmark test (using Chronoscope) on Google Chrome, Firefox 3.1 and Safari 3.1 earlier today and found that:
Chrome looks to be twice as fast as the competition on real world apps. Moreover, it's performance per Mb of memory is good as well. Even more interesting was the variation in Firefox 3.1, which appears to be related to garbage collection or memory allocation. In some runs, it was very fast, but in others, it was 50% slower.
Mozilla, you folks better do some more tests to support your existing SunSpider benchmarking test results. :-)
