Chrome is 42x faster than IE7, 9x faster than FF3

Summary: I've been testing the new Google Chrome browser and one thing's for sure: they weren't kidding about great JavaScript performance in this beta. Check out these numbers I got from running Google's V8 benchmark suite (higher is better):IE7: 30FF3.


I've been testing the new Google Chrome browser and one thing's for sure: they weren't kidding about great JavaScript performance in this beta. Check out these numbers I got from running Google's V8 benchmark suite (higher is better):

  • IE7: 30
  • FF3.0.1: 131
  • Chrome Beta 1: 1279.6

That's a whopping 42.6 times improvement over IE7, and 9.7 times over FireFox 3. Keep in mind that these benchmarks were chosen by the team that wrote Chrome's JavaScript engine (V8). Other benchmarks show a lesser, but still significant, improvement.

Unlike Adobe's Tamarin engine, which is used in Flash and will appear in a future version of FireFox, V8 (see project page) does not rely on static typing to achieve its excellent performance. It dynamically figures out what data types you're actually using as the code executes and optimizes for those types. Conventional wisdom says that dynamic types are slower than dynamic, but the V8 team in Denmark has demonstrated that's not necessarily the case.

  • Pretty amazing!! It seems like we DO need competition to foster innovation.

    • Yes we do need competition.

      Linux, Mac OSX, Windows, Safari, IE, FF, Chrome. I imagine this will spur the MS group to seriously hunker down. They are really behind. Interestingly I've tried to get my family to use FF but they prefer IE. One of my younger boys uses FF because his games load faster. Everyone else including my college age daughter always use IE. I'll wait a while on Chrome and let it "bake" then we'll see.

      Had MS worked harder on standards earlier they could devote more resources to performance. Right now the release of IE8 will be ho hum.
  • Wait, you used *Chrome's* test? :)


    Seems that the company's own benchmark would concentrate on things that make it faster than the competition.

    Besides, this is just the Java engine. Hopefully most sites stay as far away from that as they can.

    Of course if Chrome didn't have some sizzle to show, who would care?
    • He noted that clearly in the article. And, right here, right now,

      JavaScript rules the interactive web. The biggest thing holding it back has been performance. That has just been fixed.
      • yeah, right...

        I also believe everything the sales persons at GM, Ford, and Chrysler dealerships tell me about their own cars and about their competitors' cars.

        Super fast javascript - maybe. Slow Flash - maybe. I'll wait for 3rd party tests and confirmation.
    • The difference between Java and Javascript?

      Do you know?
      • difference

        javascript has a java-like syntax and is not precompiled (it's a "script," which is usually a text file). Java is a compiled language, but it is compiled into a platform neutral set of instructions called "bytecodes" rather than machine code, and that bytecode is translated at runtime into machine code by an application called an interpreter (the interpreter itself needs to be built for any platform that wants to run that language). Java runs in a browser by using a plugin (it really isn't a part of the browser) while javascript is part of the browser.

        Scripting languages (usually text file scripts) include
        Windows .bat files, UNIX shells (csh, ksh, bash), perl, python, etc.

        Interpreted (bytecode) languages include
        BASIC (typically), Lisp, Smalltalk, Java, anything that runs on .NET (e.g. C#, BASIC - .NET is a language independent interpreter), etc

        Compiled languages (machine specific binaries) include
        C, FORTRAN, Pascal, etc.
  • Chrome and key logging!
    • It's Open Source genius

      If you don't like the privacy of it, then change the
      code. If you have questions about the privacy of it,
      then review the code. If you can't be bothered to do
      either and still have complaints then stop using it
      and continue life as a MS sheep.
      • Great idea but...

        Not everyone has the time to customize the code of their operating system. If you do, bully for you, but I have better things to do. I am a browser user; I'm not paid to write my own.
        • Plenty of bloggers are going to scrutinize the code

          Until you have proof of spying all you can do is guess about something which is open for all to see. Its like saying the 7-11 down the street probably smells like rotten cheese without ever going there.

          All you have to do is open your eyes and allow the mind to follow.
  • RE: Chrome is 42x faster than IE7, 9x faster than FF3

    Well please, by all means, do the opposite give us an
    example of ANY javascript test that runs faster on IE. Oh
    wait, you can't.
    • Whoops - that was in reply to wolf_z

      ZDNET, it's time you revamp your commenting system - oh
      the bandwidth you could save.
  • RE: Chrome is 42x faster than IE7, 9x faster than FF3

    And yet is still broken beyond belief! Rendering sites was painful, clicking the back button only to have the sites refresh instead of going back was insulting. But I wouldn't expect any less quality from Google. Their programmers need to stop playing with the office toys and start learning how to code.

      he'd even put a big shiny Microsoft sticker on the front to make him look even more important.
    • Have you tried Google Chrome?

      Stupid troll...

    • Rockhead has never used Chrome

      I have been using Chrome all day, and currently
      posting using Chrome. So far there have been no issues
      at all. So again, Rockhead lies to bolster his belief
      in his deity of Microsoft.

      It would be funny if it wasn't so sad that he really believes the tripe he posts.

      • LINUX Version of Chrome?

        Umm, Linux for Me, so you're using the non-existent Linux version of Chrome to do all this work? Or a Windows VM? Or Windows?

        Inquiring Minds Want To Know.
        • I use both,,,,,,

          I use both Windows and Linux. But linux is my main OS for most of my systems. I have one laptop running Vista at the moment because I needed to familiarize my self with Vista when it became available.

          When chrome becomes available for linux, rest assured that I will be using it there too. Unlike Rockhead, I use multiple OS;s, but linux is the OS of choice for me.

    I have also tried Google Chrome. But do not think it is so much faster than ie7.
    But my ie7 is also tweaked with cmd prombt as an administrator: "netsh interface tcp set global autotuning = disabled".
    This tweak makes ie7 almost as fast as Google Chrome, however ie7 still lagging behind with javascript and Apple QuickTime, but this will be the improved in ie8 i guess.
    However I think, google chrome, is much more simple and streamlined.
