Firefox 2 vs Firefox 3 beta 5

May 13th, 2008

JavaScript performance comparison chart

Table 1. JavaScript engine performance (lower is better)
Test #1 Test #2 Test #3 Test #4
Firefox 3 beta 5 15.3 51.3 135.9 48.3
Firefox 2 184.5 782.8 909.6 828.2

I decided to give a try to Firefox 3 beta 5 and did some JavaScript performance comparison to see how faster it is. I used my own test script that performs object instantiations.
For a more thorough benchmark I recommend using SunsSpider JavaScript benchmark.
