How do you multitask?

by Anand Lal Shimpi on April 1, 2005 12:35 PM EST
With dual core CPUs coming out in the next few months, we're starting to develop our own real world multitasking tests to see if dual core CPUs will really improve performance in those scenarios. So I'm asking you all, let me know what sort of multitasking you all do and we'll do our best to get some of it included in future articles. Either post in the comments or drop me an email.

    Thanks for the input guys, keep em coming!

    GT - I can guarantee you'll see at least half of that by July :)

    Take care,
    Anand

    ^^^ That was me BTW ... forgot to enter my name.

    I often run Spybot, Ad-Aware, defragment, listen to music, have Outlook open, and 8 Firefox tabs open. And in the background I have seti@home running, plus AntiVir guard and Trillian (my IM client).

    Firefox with 5-12 tabs open
    iTunes playing
    Trillian
    Thunderbird
    Backgound programs: Windowblinds, M$ antispyware,Speedfan, FAST defrag2, gmail notifier, mouseware, ATi stuff, Mcafee security, Gigabyte VGA utilities, nVIdia sound controls

    Sometimes I have Fireworks MX, Dreamweaver MX and photoshop open, and the occational Word or Excel document.

    This is all using the Explorer shell.

    How about 'casual' multitasking? This is Mac specific, but you can 'translate' it to PC:

    iTunes open and playing from a playlist
    iPod plugged in and synching from iTunes
    Mail open
    iChat open and three chat windows open
    Safari open and 10 tabs open; AnandTech, Slashdot, ArsTechnica, Yahoo News Yahoo email, a couple articles from Slashdot open, a couple articles from AnandTech open, and the Ars Forum open
    Terminal open
    Four Finder windows open
    Email being typed into while people send you IMs

    If you want to up the complexity:
    Rip a CD while doing the above in iTunes
    Download a Linux ISO as well
    Compile Mozilla
    Run Mozilla

    This was 'normal' on my single CPU 400MHz system three years ago. I want to see how dual CPU systems deal with this (as a justification for buying a dual CPU!)

    Benchmarks... I don't know how to measure this. Time page loads? Time compiles of Mozilla (not bad idea)? Time launch times? Time how long ripping a CD takes? Count the number of beachballs, and how long?

    Right now, the processor I am using is a Pentium 4 3.2GHz with HyperThreading. I've heard all the flak from those who say it was a huge waste of money and that I should have purchased an Athlon 64 because they're faster and cheaper. I eventually made a leap and purchased a 3000+ (s754) on the nForce3 platform, but I wasn't impressed by it's performance with my usage. Sure they can perform faster (generally) in situations where there is only one application running. I can even admit for sake of arguement that when there are many CPU intensive applications running, the Athlon 64 will complete the tasks faster than a P4.

    But what I've noticed when I am comparing both platforms in my usage situations is that when there are CPU intensive applications running, that the Athlon 64 platform will have a much higher response time when using Windows (like clicking on the Start button, switching between applications, etc) than the P4 platform, which does those basic tasks almost instantly. Sure the Athlon 64 may complete the intensive tasks faster, but in terms of productivity, the P4 will allow ME to do work simultaneously which means more efficiency overall. I'd rather be able to work the whole time on the computer versus sitting and waiting every few moments I try and do something. I don't know how this would be able to be measured, as a lot of the real-world benchmarks I see don't focus on this end of things (they concentrate more on which CPU can perform all the tasks faster).

    With dual core CPU's coming out, I really think that in multitasking, Windows (and application) response time would definately improve. Maybe you could have a few CPU intensive apps running and measure the time it takes to switch between applications, or for the Start menu to come up...or opening a new application?

    What sort?

    Well, when I play games, that's pretty much all that runs, aside from the standard Windows, Norton services, etc.

    It's when I get into web development that I really start to multi-task: Adobe PhotoShop CS, Macromedia Studio MX 2004 apps, Notepad, uploading photos from camera, uploading pictures to server, favorite mp3 player running for music...

    Anand: Any chance you can have a "Dual-Core AMD64 / ATi R520 SLI" review up by July?

    Compiling a program, playing music, and loading web pages in a couple browser tabs.
