    hum that was some good, constructive comment

    The only thing I get from the article is that SSE3 is implemented through CPU dispatching. SSE vs. SSE2 seems to be (again, according to how Michael expressed it, maybe it is wrong or I am reading it wrong) a build time option.

    Any specialized low performance requirement you have for old hardware can probably be done on an ARM chip for even less power consumption with the same or better performance over the decade old x86 hardware.
    To others that might read this; it is only written for this child and there is no reason to get excited

    as some one who actually knows what hes talking about i tell you

    no
    no
    and no

    atom and brazos can suck my athlon xp

    32bit is sometimes faster to use on 64bit cpus and even P4 had sse

    even the top arm can suck an atom



    i have a new monster cpu now
    you know whats it good for ?
    its good only for new, poorly optimized, games
    like the CoD you probably play

    advances ?
    what fucking advances
    Moore's law does not apply anymore, and it didnt for a while now
    even so what complex thing does a 2D gui do that it needs a monster cpu

    third world countries holding first world back ?
    what the fuck are you talking about
    i know plenty of people that have money to god and never get a new computer
    why dont they ?
    'cuz they dont need it
    in fact you can run a fairly high load server on a P4

    also google cpu dispatching
    not that i expect you too understand what it means


    To others:
    KDE devs know what they are doing and it will not hurt none of users
    not the old computers, neither the newest
    cpu dispatching is a method to make this kind of things work at best efficiency (example glibc, x264, etc.)

    Why didn't I expect a different answer? Are you really that close minded? Don't bother to answer, someone with that mindset is not worth being read by me, welcome to my ignore list, moron.

    You realize that more software than just KDE is using Qt?

    It isn't disabled on builds, it is only disabled on their own binary releases.

    Yes, I realize that. As a Slackware user I am used to compile software from source. My statement was merely directed at such nonsense like

    Yes, while Gentoo well tuned can do miracles (I used it for a couple of years), some people try to use very old computers with the latest software.
    Having an old computer does not at all mean that you have to use old and unsupported software, it only means that you have to choose the software you use with regards to resource usage, which doesn't disqualify using Qt based software.

    100% CPU for music on P-III means something is wrong

    Originally posted by siavashserver
    Believe it or not, my old Pentium3 750MHz box (bundled with 256MB of memory and an ATI Radeon 7000) is not even capable of running a bare minimum install of Openbox with light weight set of GTK applications smoothly, don't even mention running LXDE, XFCE, etc. CPU usage goes %100 even when only trying to play music and whole system goes nearly unusable. Now you are hoping to run VLC and play HD videos too on these old farts?

    The best use that I have found for that box is a headless (home) FTP server and download manager.
    I haven't tested Linux 3.anything on a P-III yet, but I do have an old P-III/450MHZ box with Ubuntu Maverick (10.10) on it. If you use Audacious to play music, no sweat. I used a similar 500MHZ Athlon box as an audio playback server for years with little load on it. With Maverick, that box can play QVGA video with no issues, is just slightly slow for VGA/mpeg-4 video, cannot handle 360p/H264 video. On a Pentium 4 box I found a Quantal (Ubuntu 12.04) based Mint/MATE install to be essentially a match for Ubuntu Hardy on that same box for performance.

    Make sure that update-manager or some other background process is not trying to run and hogging the CPU on anything this old! Open a terminal and run Top, look at what is running. Update managers and things like apt's xapian index are common culprits, you cannot use them on something this old. Same goes for Pulseaudio-older machines can't handle the overhead.

    Some of the slower Coppermine or Tualitin-based Celerons used surprisingly little power at slower speeds and are thus better suited to minimally-demanding applications that they can handle than a Pentium 4, especialy a power-hogging Prescott chip. File servers, print servers, sound servers, you name it! No reason to spend $300 on an Atom box to do this, don't know if the difference between a 10W box and a 30W box can pay the environmental costs of producing a new computer from raw materials all the way back to the mine.

    A tougher choice exists when setting up web computers and Pentium 4's are what's available. Strip down to OS a bit, use alternate versions of packages compiled for newer systems, do NOT use the new style desktop environments and they work-but there an Atom/Fusion box saves a lot more power if the machine will run for many hours a day. Hell to find graphics cards for AGP versions that can play H264 in hardware, cannot play 1080p video without them. Still, I see a LOT of these in use in my community, and many people never see a single 1080p video file due to bandwidth.

    The Athlon 64 should probably be considered the "first modern processor" that modern distros need to be able to support. I've got one with a Radeon HD4350, Ubuntu 13.10/Cinnamon on it, and it can play a 1080p H264 video using VDPAU on the open driver while running the Cinnamon desktop. It can do anything my Bulldozer box can do except edit HD video or play demanding games. Yes, it supports SSE2. By comparison, Athlon XP does not, and Atlhlon Thunderbird lacks SSE entirely.
