Once I learnt above the availability of these tests, it seemed like a good idea to test the browsers on my laptop. The tests were conducted on July 1, 2011. The results are given below for the browsers I tend to use [Browser Performance is tested against ECMA's Test262 Version 0.7.5.1, 30 June 2011, with 10934 tests]:
|Browser ||Version ||Time to Run (min.) ||Pass ||Fail ||Fail to Load |
|Mozilla Firefox ||5.0 ||42 ||10,662||262||0 |
|Microsoft IE||9.0.8112.16421||20||10,634||300||0 |
|Google Chrome ||12.0.742.112||55 ||10,427||507||0 |
|Opera ||11.50 Build 1074||46 ||6,995||3873||66|
|Apple Safari ||5.0.5 (7533.21.1)||Crashes after ~2,500 tests in a little after 5 hours!||~2,500||20||~8,414|
The biggest surprise is that some of the browsers do not load all the tests; and, Apple Safari is the worst performer from this perspective, not being able to load more than 75% of the tests even after 5 hours of execution! And, Opera failed more than 35% of the tests!
Firefox, IE and Chrome have had the least hiccups, were able to load 100% of the tests, but failed 1.4%, 1.6% and 2.7% of the tests respectively.
All the tests were run on an ACER Aspire 4730Z, Pentium Dual-core CPU T4200 @ 2.00 GHz with 3GB RAM and Windows Vista Home Premium Service Pack 2, 32-bit. It takes about 50 minutes to run the tests on each browser.
