Firefox has finally managed to overtake Google Chrome in the latter essay συγκριτικής αξιολόγησης SunSpider στα Windows 10 64-bit.
Performance data was published by Mozilla's JavaScript team on site Are we fast yet, which tracks the performance of its JavaScript browser and compares it to Chromium.
The chart above shows that Firefox has been able to overtake Chrome over the past two months. Tests are conducted daily. Performance is measured through execution time (in ms), so the lower the points on the graph, the faster the performance.
For those who don't know, SunSpider is a complex benchmark designed to test JavaScript performance.
It was released for the first time 2007 by WebKit, and is a legacy reference standard at the moment, last updated in 2013. Since then it has been superseded for about a decade by newer benchmarks like Google's V8 and Octane. That's why the victory, although commendable, may not be particularly important.
Meanwhile, in Apple's JetStream 2, which is another complex test for measuring JavaScript performance, Google's Chrome continues to outperform Firefox, and the gap is almost as wide as ever, although Firefox is slightly ahead improved.
Finally, as you will see in Are we fast yet, in the Speedometer, which also measures the performance of JavaScript, among others Firefox has been lagging behind recently, even though at one point it managed to catch up and slightly surpass Chrome.
