WhenSafari 5was unloose Monday , Apple claim that the “ world ’s truehearted ” Web browser app is now truehearted . Macworld Lab fly the coop a performance test on the new Safari , and our result confirm that Safari 5 provides a cost increase over its predecessor — at least when it comes to the internet browser ’s JavaScript engine .
We used theSunSpider JavaScript Benchmark , which focuses on Safari ’s Nitro JavaScript engine . Apple claims ( on theSafari website ) that Safari 5 is “ up to 30 percent faster than Safari 4 , 3 percent quicker than Chrome 5.0 , and over doubly as fast as Firefox 3.6 . ” Apple also apply the SunSpider mental test .
In our testing , Safari 5 ’s JavaScript functioning was 19.2 pct faster than Safari 4 ’s . That ’s nowhere near “ up to 30 percent ” claimed by Apple , but there are a batch of variable that come into romp affecting the results . The most important factor is the Internet connection — experimental condition can vary found on dealings and routing . Still , a boost of most 20 pct is significant .
Shorter bars are better. Reference software in blue and italics. How we tested: We ran the SunSpider JavaScript Benchmark on each Web browser. Our test platform was a 15-inch 2.4GHz Core i5 MacBook Pro with 4GB of RAM running Mac OS X 10.6.3.—Testing by Blair Hanley Frank
As for the other browsers in Apple ’s call : equate to Chrome 5.0 , Safari 5 was 3.5 percent faster in our test . Safari 5 was well over double as tight as FireFox 3.6 . Our results actually find Safari 5 quicker than what Apple claimed — again , Internet connectivity can influence test solvent .
Apple did n’t mentionOperain its speed claims , but we essay Opera 10.53 . We find that Safari 5 was 11.5 percent faster .
One thing to keep in brain is that the differences are measured in millisecond , so you may not be able to sense a remainder between Safari 4 and Safari 5 .
