Question about Vist processing speed

I bought a new Vista machine about two weeks ago and it is, if anything, slower than
my 6 year-old XP machine. In fact, it is slower than my XP machine was when it only
had 512MB of RAM. My new machine is an HP Pavillion Elite with 3GB of RAM and
an Intel Core 2 Quad processor. I expected to see a substantial performance increase
over my old PC but was very suprised to see that it's actually slower... substantially
so with some applications. But I just noticed something that may help explain
what I am experiencing and I wonder if someone could explain this to me. With
my old PC, when I ran a single resource-gulping application like editing huge files
in Photoshop or encoding videos, etc., it would run that application using as much
CPU as it had available. If no other apps were running, that app might be using 98-99%
and the ran very quickly. That made sense to me because what it seems to me that
the PCs power should be used, not left in idle. Of course, when I ran several apps,
it divided the CPU up between them and I could adjust their priorities in Task Manager
if I liked. But with my new PC, I just noticed while running a single application
that it is only using from 0-1% of CPU and the system is running at an average of
98% System Idle. Is it normal that a Vista machine doesn't use it's power like this?
It's nice that it's running the job with it's hands behind it's back, so to speak,
but it seems to me that it should utilize the power that it has on hand and speed
up the app that is running. Are there settings that would change this behavior
or is it something I will just have to live with with Vista?

That's more of software that isn't programed to utilize all 4 cores than a Vista
problem.You will be seeing more multithreaded apps come along but technology has
just outstripped programing.Try running 4 things at once and you will see the speed
improvemnt.

Thanks jbm. I did run three or four resource hungry jobs at once and they each
used only from 0-1% (at most 2%) while the system sat at about 99% idle. However,
I see a partial explanation for that now. One program's settings were defaulting
to run in the background. I changed that and now it runs faster. The version I
had of that program on my XP machine was older and it probably didn't have that setting.
One of the other jobs was the backup built into my PC and maybe that is set to
run in the background too, which makes some sense, and I will check that out. On
the other hand, I encoded some movies yesterday and they blazed along, taking less
than two minutes each when they took probably an average of 15 minutes on my XP machine.
So it looks like I just have to see if the slow running programs are set by default
to run in the background. At least I now know that when an application is allocated
enough CPU, it can run fast. Thanks much.
