Apple upgraded its browser to Safari 4.0.3 yesterday, which fixed 6 security vulnerabilities and improved browser performance and stability. Not to mention the Mac platform for the time being, this upgrade makes Safari 4 more effective in many aspects on the Windows platform. The speed has been greatly improved, such as page rendering. However, the poor performance of AJAX performance has caused the overall score of Safari 4.0.3 to not increase significantly.
According to the test results of BetaNews, the score of Safari 4.0.3 on the Windows XP SP3 system has declined compared to the previous version, from 16.16 to 16.01. However, its score on the Windows 7 RTM platform has increased, from the previous 12.58 It grew to 13.09.
What is puzzling is that Safari 3.0.4 performed very poorly in the AJAX performance test, even worse than IE7 on the benchmark Vista SP2. When testing the time to create the XMLHttpRequest object in the browser JavaScript, Safari 4.0.2 took 23 ms and scored 8.96, which means that its speed is 8.96 times that of IE7 on Vista. However, Safari 4.0.3 took 371 ms, the score is only 0.56.
Released almost at the same time as Safari 4.0.3 is the latest beta version of Opera 10, Beta 3. Let’s take a look at its test results: Beta 3’s score (5.07) on the Windows 7 RTM platform is higher than Beta 2 (score 5.31). Despite the drop, the score on Windows XP SP3 remained unchanged (still 5.28). What’s interesting is that Opera is the only browser whose stable version and beta version perform worse than Vista on Windows 7. Opera 9.64 and Opera 10 Beta 3 scored 4.40 and 5.07 on Windows 7 RTM, and on the Vista system The scores were 4.43 and 5.27.
