Firefox 4's JavaScript Now Faster Than Chrome's

Posted by timothy on from the when-browsers-jostle dept.

An anonymous reader writes "Firefox 4's JavaScript engine is now faster than V8 (used in Chrome) and Nitro (used in Safari) in the SunSpider benchmark on x86. On Mozilla's test system Nitro completes the benchmark in 369.7 milliseconds, V8 in 356.5 milliseconds, and Firefox 4's TraceMonkey and JaegerMonkey combination in 350.3 milliseconds. Conceivably Tech has a brief rundown of some benchmark figures from their test system obtained with the latest JS preview build of Firefox 4: 'Our AMD Phenom X6-based Dell XPS 7100 PC completed the Sunspider test with the latest Firefox JS (4.0 b8-pre) build in 478.6 ms this morning, while Chrome 8.0.560.0 clocked in at 589.8 ms.' On x86-64 Nitro still has the lead over V8 and TraceMonkey+JaegerMonkey in the SunSpider benchmark."

    FF4 crashes when I try to open Gmail since the change. This makes it slower for opening my mail.

  3. What Mozilla giveth, Slashcode taketh away. by Anonymous Coward · · Score: 5, Funny

    Why do I have a feeling that Slashcode's terrible AJAX interface is going to get even worse in the near future?

    This is quite possibly the lamest e-peen measuring contest ever.

      Yea, what is even more irritating is they keep subjecting us to it. Even thought the boxes stay checked I have had to go to my user preferences and turn on and then back off the new comment system several times in the last two weeks. I hate it, based on the comments I read here on Slashdot just about everyone else hates it two. Some of them are just Luddites that want the Slashdot of 1997 period but the rest of us just hate because its an awful way to browse and read comments, awful (GET IT TACO AWFUL) so many other sites have gotten it write, if you feel he need to update the look and feel of Slashdot go look at what others are doing!

  4. and yet Firefox still can't use 1 core... :( by electrosoccertux · · Score: 5, Insightful

    Tell me, mr anderson, what good is javascript performance if you are unable to use multiple cores?

    I wish someone would get on this and make firefox work with multiple cores better. As it is I use the "|" character in my home page settings to open about 20 tabs-- forums, review sites, slashdot, economics blogs, etc....and firefox slows to a grinding halt for about the 15 seconds (just timed it) it takes to render all those pages.
    Chrome does it in about 4 seconds and pegs all 4 of my cores to 100%.

    Please Mozilla, I know this would require a serious redesign, but it's seriously needed. Hitching while scrolling up/down because a tab is loading in the background (I make use of middle click to open tabs in the background extensively) is very annoying.
