Firefox 3.5RC2 Performance In Windows Vs. Linux

pizzutz writes "Andy Lawrence has posted a Javascript speed comparison for the recently released Firefox 3.5RC2 between Linux (Ubuntu 9.04) and Windows(XP SP3) using the SunSpider benchmark test. Firefox 3.5 will include the new Tracemonkey Javascript engine. The Windows build edges out Linux by just under 15%, though the Linux build is still twice as fast as the current 3.0.11 version which ships with Jaunty."

    Firefox isn't slower because of ubuntu, it's slower because the microsoft's C compiler is better than gcc.

    This proves that, um, Windows,er, Linux is....um...what the fuck does this prove again?

    And why the fuck should I care if there's a 15% difference in performance of Firefox between those two OSes? I use my particular OS for reason that have nothing to do with how well Firefox runs on it.

    That 15% could very well be measured in hours when the Slashtard coders get through with their Web 2.0 abominization of Slashdot.

  3. maybe linux carries some of this blame by asa · · Score: 4, Insightful

    Putting the blame all on Firefox when there's no doubt a certain amount of performance penalty that comes with a Linux's less good compiler is just lame. How about telling the linux tool makers to build tools that output faster and smaller code instead of demanding that app developers solve those problems? Finally, what "linux" build was this? Did it use profile guided optimization and other performance features of Mozilla's official Windows build system? If not, you're comparing apples to oranges.

  4. Re:So what shall one use now? by asa · · Score: 4, Insightful

    A very large chunk of Firefox's developers have Linux as their primary platform. Linux Firefox absolutely doesn't get crap treatment from Firefox developers. You're obviously not familiar with the comparative qualities of the compilers on different platforms or you would asking "why do the Linux compilers get beat so badly by the Windows compilers."

    I am SHOCKED and AMAZED that a compiler specifically implemented for x86 (with assistance from Intel) produces more efficient x86 machine code than a compiler that is based on a general purpose architecture with just a back-end code generator for x86. Next you'll be telling me that a Swiss army knife isn't as good for skinning animals as a Bowie knife and that an amphibious vehicle is neither as fast on land as a Ferrari nor as fast in the water as a cigarette boat!

    You know all that stuff that's running in the background. Well, it's running in the background, which means that most of it should be swapped out and it shouldn't wake up very often to do stuff.

  7. What about other common cross platform software ? by godrik · · Score: 3, Insightful

    Are there around some tests about other open source software that could help us understand the problem ? We can find some on open office : http://www.oooninja.com/2009/03/multiplatform-benchmark-30.html Or Tomcat : http://mediakey.dk/~cc/tomcat-performance-linux-faster-than-windows/ But that does not seem to gie a clear understanding of what's happening.

    It's /. and it's sorry assed javascript, not firefox.
    I went to preferences and chose 'classic view' to end this assclown behavior. That also ended the funny bars showing up in the middle of replies, the friend/foe icons plastered on top of comments, and other asshattery that was going on here also.

    They also have an easier job. MSVC doesn't need to address as many architectures as GCC does. IIRC, there is no MSVC for s/390

    Just because you can justify Linux's inferiority in this one area doesn't mean that we don't need to improve it.
