    I'd like to know if anyone using a single core processor has noticed any
    significant improvement in performance after upgrading to Windows Vista or is
    it only those with Dual Core processors that are noticing significant
    improvements to performance? (Please, this question is for those who were
    previously running XP with the same hardware, if you’ve increase your RAM or
    made other hardware upgrades then it's hard to determine if your performance
    improvements are really due to the new OS.) Thanks

  2. Memory dims. A person who upgrades soon forgets how Windows XP use to run.

    A better question would be asked of those who dual boot.

    I dual boot so, obviously, the exact same hardware is used no matter which
    operating system I use.

    I have found that now I boot into Windows XP every 2-3 days - just to update
    the antivirus and anti spyware programs. I then immediately reboot and use

    I set my computer up from scratch with Windows XP on the second partition so
    that when I was totally satisfied with Vista I would eventually delete the
    XP partition and claim the space for my D: partition. I am very close to
    carrying out that option.

    So, I guess that must answer your question. If Vista were a dog I would be
    doing just the opposite.

    Thanks for your reply Richard but you don't actually answer my question. Are
    you using a single core processor or Duo core and if you are using a single
    core have you noticed SIGNIFICANT improvement to system performance?

    I do not think Vista is a dog. The difference in performance on my laptop
    with a duo Intel processor (T2400) is night and day.

    When I first got my laptop a year ago, with XP pro, I was very disappointed.
    There seemed to be little improvement in performance over my previous laptop
    with a Pentium M 715. That was the case right out of the box, on a new system
    and nothing installed. But the moment I installed Vista there was such a
    difference in overall performance it was hard to believe it was the same
    Now there are those who are telling me it’s due to the fact I’m using dual
    processor and Vista is better able to take advantage of dual processing power
    over XP. Does that mean those who are using single core processors shouldn’t
    expect to see much improvement in performance over XP? (That doesn't mean
    it's a dog, just that performance will be pretty much the same.)
    The article I provided a link too says pretty much the same thing: I want to know how true it is?

    So, as much as I appreciate your comments, you haven't answered the
    question. I don't know what kind of processor you are using and telling me
    Vista isn't a dog doesn't mean anything. Have you noticed any significant
    improvement in overall performance over XP and what kind of processor are you

    For my part I wouldn't go back to XP for anything. I have some minor
    software issues with Macromedia Fireworks 8 that are a little annoying, but
    I'll put up with it. My computer has taken off since installing Vista, it's
    awesome, but should I be telling friends it's due to the fact I'm using a
    dual processor, that's what I want to know. Let's get some feedback from
    those who are using single core processors.

  4. I have a single core processor (Athlon XP 3200). You said "on the same
    hardware". If I switched my hardware to be dual core that would not be the
    same hardware (CPU, M/B and RAM).

    Of course dual core will be faster - even a low to medium processor and 2
    gig of the appropriate RAM will beat out what I have now.

  5. Any upgrade like that will improve performance, but it may not show directly
    in the things that you want to see improved.. where applications are more
    reliant on CPU performance than RAM, sure you will see an improvement..
    whether it is as much as you would have hoped is another ball park.. if you
    are just looking for lightning fast boot ups et al, then fit the meanest,
    fastest, most expensive parts you can afford or that can be bought..

  6. Scary, isn't it.. yesterdays top systems are today's budget line.. I don't
    care if my video card only stumps up 3.7 on the Vista scale.. and the fact
    that I keep looking for something really cheap that will at least show a 4
    is totally immaterial.. :)

    Thanks again Richard, but that's still only half the question. You still
    haven't told me if you've noticed a significant overall system performance on
    your single core with Vista or does it run pretty much the same as XP.

    I want to know if single core users are seeing much of a performance
    improvement over XP. You'll notice there are a lot of people (like myself)
    who say their system is screaming now that they've switched to Vista, while
    others aren't seeing much improvement. I want to know if this is at all
    linked to dual cores. That is, Vista may be far better in taking advantage of
    dual core technology then XP meaning people with dual cores who are switching
    would notice a sudden increase in performance while those using single core
    would see as much of a change.

    That's what the article suggests. I know there are other factors, such as
    driver issues, but I was curious to see if anyone out there using a single
    core has noticed SIGNIFICANT performance improvement since switching to
    Vista, obviously if they did hardware upgrades, I couldn't be sure if the
    improvement was due to switching to Vista, while in the case of my computer,
    I know all that I changed was the OS, and I saw a significant improvement;
    was that only because I have a dual processor?

  8. I used to run XP in classic mode on a single core.. it performed better that
    way.. for me, Vista runs as well or better even running the full Vista
    graphics on exactly the same machine.. I quit booting into my Vista
    installation long ago because there is no point other than to update it, and
    I don't even have XP wireless card drivers installed such that I could even
    do that anymore..

    I don't know if you read the article but it claims that a duo core system
    under Vista can expect a 5 to 30 percent improvement in performance while
    single core systems may actually see a slight slow down under some
    circumstances. I'm curious as to how true this is. Are there users who have
    found otherwise?
    black clouds, Mar 24, 2007
  10. I thought that I stated as much when I said I boot into Windows XP every 2-3
    days just to do maintenance and then immediately reboot into Vista to do any
    work. If XP were better/faster - it would be the other way around.

    I am extremely happy with Vista, even on my single core processor.

    For my needs, there is little need for dual-core. A beefier video card
    might prove cost effective, but spending on AGP technology is a poor
    investment in a PCI-E era, which the MB doesn't support.

    I have have dual core processor and am running Vista with the exact same
    hardware that I was running XP on. I would never go back to XP, because
    Vista is very much faster.

    All I'm trying to see is if there is any truth to Vista being able to handle
    duo processors better then XP. It may be a stupid question for you, but it's
    not for me. I may have written poorly, but perhaps not.

    I'm not talking about upgrading any system. Nor am I suggesting Vista is a
    poor OS. On the contrary, if Vista is able to handle duo processors more
    efficently then XP, I see it as a plus and another reason (among many) to
    upgrade to Vista if one is running a dual processor under XP. Unlike some, I
    don't like having to sit around waiting for programs to open or information
    to be processed. It's one thing if it happens once or twice a day, it's
    another matter if one is multitasking and has to put up with it all the time.
    I like to see things responding quickly and efficiently so I can get on with
    other things.

    I'm not talking about running out and buying a dual core I already have one.
    However I would like to know why I (and others) have seen a significant
    improvement to system performance while others have not. Richard told me he
    wouldn't use Vista if it ran like a "dog," well that's obvious, I'm not
    suggesting he's stupid, but it doesn't mean he's seen any significant
    improvement either. Of course even without any improvement to performance
    there are still plenty of other reasons to upgrade. Performance isn't
    everything, but it is important. I'm sure you wouldn't put up with a system
    slow down now would you?

    Christopher Null suggests that Vista does significantly improve the
    performance of dual core systems over XP, I want something to confirm that,
    before I put my neck out on the line and suggest the same thing to others. I
    saw improved performance by switching to Vista but was it really due to Vista
    being able to make better use of my dual processor or was it some other
    factor? Are there others who can confirm or deny that Vista is able to better
    utilize dual core processors then XP.

    Perhaps you will say, "Of course it can, dual cores were not a factor when
    XP came out." Well let's confirm it with facts. I want to hear about the
    experience single core users are having. Have they seen any major performance
    improvement under Vista or is it running pretty much the same as under XP,
    because if so, that may explain why dual core users are seeing significant
    improvement. Obviously well there is little Microsoft was able to do to
    improve performance over XP in regards to a single processor, they have made
    improvements were they could, taking advantage of other newer technology.

    It would certainly help me understand why I saw a major jump in performance
    by simply installing a new OS, while others have not seen the same thing. Or
    do you have so other suggestion or perhaps you can show me there is no
    difference between Vista and XP's handling of dual processors. After all,
    that's what I'm here for, looking for answers.

    On my Tablet PC (Toshiba Protégé M200), Windows Vista seems faster, I've not
    actually benchmarked it, but booting up, getting a useable system doing
    normal every day things on it seems faster. I'm still dual booting on it
    and booting XP is a pain, it just feels slow in comparison.

    This is with a 1.8Ghz Pentium M (that's single core) and 1GB of RAM.

    I have a Intel 3.4 Prescott with 2GB of memory and Vista is faster and XP on
    my setup. Your could be different than mine do to your hardware setup.

    I think your assessment is correct - building this year's PCs on Vista
    with 512M RAM and 1G RAM, they feel about the same (1G) or a bit
    slower (512M) than XP PCs built with similar specs late last year with
    512M RAM. Vista feels a bit slower or similar, but certainly not
    massively faster than XP, and Celeron and Pentium 4 of similar clock
    speed feel much the same as well.

    So I think it's better use of the dual cores that is working for you.

    Saws are too hard to use.

    I don't know if this can help with your question, but I have an Intel Core 2
    Duo 6300 running at 1.86 Ghz, 1Gb of RAM, and I used to have XP, running
    really fast. I installed Vista Ultimate a few weeks ago, and I can tell you
    that my computer is slightly slower with Vista... So I'm buying a new Video
    Card and 1Gb of RAM to improve it...or at least so it can run as fast as it
    was with XP....

    I have noticed a difference on my system. I am running a dual core pentuim d
    3ghz cpu, in a triple boot system. I still run xp since some of my hardware
    is a little dated (printer for one). But, my vista runs faster than the xp
    but my linux is still the fastest.
