Contrary to Apple's claims, the newest version of Safari is not the world's fastest browser, benchmark scores show. But it is dramatically faster than rivals being built by Mozilla and Microsoft.

That new engine was most in evidence when Safari 4's scores are compared to those of Safari 3.2.2, the current shipping version on Windows: The beta of Safari 4 was about 3.7 times faster.
Safari 4 also proved faster than the newest Firefox, a nightly build in the run-up to Firefox 3.1, although at just 38 percent faster its edge was much smaller.
It easily beat Firefox 3.0.6, Mozilla's production browser, and IE8 Release Candidate 1 (RC1), Microsoft's latest public release of its still-under-construction successor to the three-year-old IE7. According to SunSpider's tests, Safari 4 is nearly 3.5 times faster than Firefox and about 5.6 times faster than IE8.
