Hello,

I have a xp core duo 2 machine at my work with 500mb ram (desktop) and vista
ultimate core 2 duo at home with 1gb ram (laptop).
I use a statistics package for my calculations.
While the comp at my work does the calculations in say 10 seconds, my home
comp does it in 20 seconds.
Where might be the problem?
Why my desktop is faster than my laptop?

thanks in advance for answers.
 
Probably a difference in processor and hard drive speeds. You didn't give
much hardware info.

In addition to what Mark wrote about processor and hard drive speeds,
one should consider the amount of available memory. Your XP with 500MB
RAM may have more available memory than your Vista with 1GB RAM.

I would recommend a minimum of 2GB RAM and a 256MB video RAM for Vista
Ultimate, which are both substantially greater than what Microsoft
recommends as the minimums. The difference is between simply allowing
it to run and getting decent performance.

Many of the people that complain about system performance under Vista
are simply underpowered. Yes, it is a fact that Vista requires more
hardware. I say to them, get over it. XP required more than 2000,
which required more than NT, which required more than 98 and so on.
Your cell phone probably has more compute power than NASA used to put
a man on the moon, but you still wouldn't try to put a man on the moon
with your cell phone.

IMHO, it is a sad thing that so many OEM's are still selling Vista
preloaded on machines that shouldn't have it. If you want happy
customers, then make sure what you're selling will have enough power
to perform. OEM's should quit doing that. Microsoft should increase
their minimum recommended configuration to a minimum standard of
performance, or an XP equivalency rating.

To "Recover" or restore performance to Vista one consideration is
whether the user requires extensive search capability. If not then a
change to Windows Search will lower the overall system loading.
While indexing has value, it tends to become a persistent drag on
the performance of Vista and if the user doesn't need the capability
then allowing it to run may not be needed.

Pfffftt.

Xp "required" ~50% more than 2000, and in fact runs perfectly well
on systems well under minimum spec. Vista requires 4x the hardware XP
does, and then runs only in a sort of approximated mode.*

And dont' hand me that nonsense about a new OS simply requires
new hardware. EVERY OTHER VENDOR IN THE WORLD writes their new release
to the current hardware, and as hardware improves their users take advantage
of the new feature set. Only MS writes operating systems that don't run
unless you have cutting-edge systems.


* XP: 233MHz cpu, 64MB ram, 1.5GB disc, Vista: 1GHz CPU (4X), 512MB RAM (8x),
40GB disc space + graphics requirements, 2000: 133MHz, 64MB, 640MB disc.

Worse, the vendors often claim their hardware is ready by slapping on
a Vista Certified logo when it is shipped WITHOUT the necessary Vista
drivers having even been released yet. There ought to be a law...

Microsoft is one of the most hated corporations in the world. Geez, I
wonder why that is. Hmm...

When was the last time you saw the CEO of Procter and Gamble or IBM
get egged or have a pie thrown in their face? Never happens. Yet both
these things happened to the top two executive of Microsoft.

Still the mentally retarded fanboy crew sing Microsoft's praises.
Damn funny.

What other vendor? Apple? Not true. Each release of Mac OS required
more than the last. A big difference is that Apple sells Apple
computers. Microsoft doesn't sell Microsoft computers. We could talk
about MVS, or Solaris, HP-UX, but it wouldn't matter. I think that
both Microsoft and PC makers need to change the way they sell and what
they market as a minimum configuration. A minimum recommended
configuration should provide better performance than the last
generation.

Its no secret that Microsoft is bloatware and they constantly throw
more stuff in; but, such is their market. One might even make
reasonable arguments in favor of Apple or Linux, but it doesn't really
matter either. Microsoft is ubiquitous. Apple might be popular in arts
and education, Linux has yet to penetrate the home market; but,
Microsoft is the de facto standard for business.

IMHO, Microsoft made a gargantuan mistake with the recommended config
and OEM's happily sold it to an unsuspecting public. Cie la vi!
Microsoft so dominates the market that it has barely even bruised
their egos. I think they hear the voices of disgust, but they aren't
likely to change their roadmap despite the heavy criticism. If I ran
Microsoft, I would demand an equivalency performance rating and
configuration recommendation. Consumers wouldn't be so upset, if Vista
were only installed on configurations that could truly handle it,
which would mean a longer life for XP. You see it on these boards
every day. In a couple of years, it won't matter.

Sun. IBM. HP. RedHat. QNX. SCO. Hell, even ID and Epic

Why? Because it doesn't support your wrong-headed assertions?
 
Hi minimus,

There are several reasons why you are experiencing the difference in
performance between the 2 machines, and I shall list them below in no
specific order. These should give you some idea as to why there is a
difference in apparent performance.
Dwarf

1) You are using 2 operating systems, XP and Vista. The system requirements
for Vista are higher than that for XP.
2) Power configuration. A desktop machine is connected to the mains, so runs
at maximum performance. A laptop is more often than not run on battery power,
so the power settings are set to take account of this - everything is
underclocked. Lower frequencies means less power required, which in turn
gives greater battery life between recharges. Of course, if you run the
laptop with an adapter connected, you can change the configuration to give
you maximum performance as opposed to maximum power saving.
3) Memory. In most modern desktops memory can utilise dual channel mode,
thereby doubling the amount of data transferred to and from the memory with
each clock cycle. Very few, if any, laptops offer dual channel memory
capability.
4) The version of the software you are using.
5) The actual configuration of your machine. Software running in the
backround and, on the Vista machine, the 'Aero' settings.

dear all,
thanks!
I think I have some ideas.
Maybe I will upgade to 2 ram first....

minimus,

RAM is cheap. I would suggest upgrading to 3GB and letting Windows
manage your pagefile..

I don't blame them at all. Most people don't buy Porsche, Farrari, or
Corvette because they don't need that kind of performance and/or they don't
wish to spend money on cars (regardless of they can afford or not), and it's
the same as they don't see the benefits of owning a powerful computer.

What system builders are doing is simply responding to the demand from their
customers based on the amount of money that they are willing to spend on the
item, just like you would for a car, dress, house, and so on. It's nothing
new and it has always been like this.

What will you do If a car dealer will sell you nothing but a Porsche or
Corvette? You would just buy it or turn to another dealer? What will
happen if the entire market has only those two or three cars?

You could try to "educate" customers for the "benefits", but still, it's up
to them to decide if those benefits are practical or relevant, and more
importantly, if they want to spend money on it.

The market is moving toward low-price and commodity-like systems, and that's
how the majority sees the value of computers.
Microsoft should increase
their minimum recommended configuration to a minimum standard of
performance, or an XP equivalency rating.

Agreed. My view is that they want to cope with the market trend for the
purchasing cost except the product doesn't meet that standard.

Yes, exactly right. I would estimate that Vista with 2GB is roughly
equivalent to XP with 512. They should not be selling 1GB Vista machines
at all really.

One gig is just fine with Vista Home Basic... but finding a machine
with that isn't easy unless you order it custom built.

I have found that Vista runs slightly differently on machines of the
same basic spec, you know, maybe the difference is just a later version
of the same motherboard, but ultimate seems to definitely benefit from
2GB or more on all the ones I have built. I don't dispute that some
machines with 1GB are okay, but for what RAM costs to the manufacturers
it seems foolish to risk their reputations to save a few dollars.

Mine's a home-built and it's just as fast as XP was was.
