IE10 shows the most remarkable improvements in the Kraken and SunSpider benchmarks, while RIABench and Peacekeeper only reflect a marginal improvement over IE9. Chrome is the hands-down winner, as it has been for nearly the entire lifespan of Google's browser.
DOM (Document Object Model)
We use the DOM Core subsection of Mozilla's Dromaeo DOM tests to represent DOM performance in our final scoring. The Dromaeo results are an average of two iterations.
2. I find the over-reliance on "Internet Explorer Test drive" benchmarks disturbing. Most use code that is inefficient and not used anywhere else on the web, making it quite theoretical.
3. +1 for using Google Octane benchmark. Both google and mozilla agree that this is a good real-world benchmark.
4. Addition of the "Maze solver" benchmark is disappointing.
5. Why remove the subjective smoothness ? 95% of the time, subjective smoothness is what lures a person to use a specific browser. People use a browser, not run benchmarks on it all day. Subjectively, no browser can beat Google Chrome. Then comes Opera , Firefox and far lastly, IE10.
Games and applications did not show any improvement in Win8 over Win7.
2) The only IETestDrive tests we use are Psychedelic Browsing and Maze Solver, and IE regularly loses to competitors on both.
3) Octane was not used because it had issues with IE9 and Opera 12.10.
4) We definitely need a new CSS test, but the only other options are outdated or on IETestDrive - unfortunately, Kaizoumark doesn't work with IE10.
5) It's really difficult to see that kind of stuff on a modern test system, but I will say that Chrome and IE10 are about equal in that department, with Firefox and Opera noticeably more choppy right at the beginning of the 40-tab load.
1. IMHO, enabling these settings would have made Opera more competitive and this article fairer.
3. Whoops, misread that. But this is a good benchmark. Robohornet and robohornet pro are complete jokes.
4. Just exclude the maze solver. Its bad coding, as any web developer can tell you.
5. Thats exactly what i'm saying. This needs to be factored in the overall score. You want the browser UI to always remain smooth. UI choppiness is unacceptable and sloppy coding. We are not living in the 90's anymore.
The one thing i dislike in Chrome is the memory bloat when opening many tabs. In the 40tab test, FF uses 600 MB. Chrome uses 1600MB :O. That is probably an iverhead of using separate processes for each tab. That is excellent for smoothness and UI fluidity. But shameful for memory consumption. I guess devs need to find a middle path.
Plus, they heavily test features that are not used anywhere else on teh web.
Example : Sunspider makes a billion manipulations to the the "date" variable. Mozilla did not have any optimization for this. So it scored poorly on Sunspider. After numerous 'review sites' started using sunspider to test FF Vs Chrome, mozilla developers had to reluctantly add the same optimisation (which is basically a separate buffer to store the date). Of course, nowhere on the web is the date variable used in this manner. So its optimization for an artificial test.
As far as I heard there are significant under-the-hood improvements in Win8, in terms of memory efficiency and multi-core usage.
