How does Vista perform on an dual proc machine ?

I'm particularly interested to know this since all the versions of Windows
I've used appear to freeze whenever there's a problem with a Subsystem I/O
activity such as network acces, disk, etc. I'm assuming that this is a
kernel design issue, since the OS isn't really Multi-tasking but
co-operative tasking.

Seems to work OK on mine... haven't seen any major performance issues except
actual Vista ones which I've got even on one of my more basic machines.

Obviously it's slow and all, however I'm probably taking into account the
fact that performance hasn't been set and Glass does take a lot of stuff up.
So probably over all... yeh it's slow for what my machine should be *-)

It will be slower on an Intel Core Duo, faster on an AMD Dual Core. Since
Intel Core Duo procs cannot talk directly to each other, do not have on-die
memory controllers, can't have both L2 caches working at the some time, have
no Hypertransport bus, and have not Direct Connect architecture, they cannot
run the OS as efficiently.
FWIW, the Vista Development team is using AMD Athlon64 processors for its
testbeds...that should tell you something. At the risk of starting a war
here, AMD X2 and Intel Core Duo are significantly different from each other.
In 32 bit, the difference is not very noticeable. With Vista, the difference
in the two architectures is *very* apparent.

Running it on dual 3.06 Xeons and painfully slow but then MCE2005 doesn't
exactly race along either.

I am not guru on writing kernel mode things, but I do know that vista has
cancelable io, this is new and I think it may help prevent hangs or will it
make writing drivers easier so they are better, not 100% sure, but I am sure
the answer is only a Google away, I've just done a Google , didn't find much
, but I was at a vista training session a few weeks ago and this was one of
the topics, maybe I have to the name wrong.

I know from my Unix days, that certain hardware does not play well with
multi tasking, LPT ports was one of these, I do think windows is multi
tasking though, maybe its some badly written drivers that has caused you
problems.

I have a dual core, and its working fine, I do get the odd freeze, but.....
is it freezing or is it the GPU drivers going a bit funny. it would be
interesting to write a program that counts, see if that counts drop when it
freezes :).

Yep, http://www.neoseeker.com/news/story/5418/
Unlike the Core Duo, each execution core is not independently clocked nor
powered, so if one core is doing all the work, that means that the other one
is running at maximum speed and voltage the entire time. With the Core Duo,
each core can adjust itself, depending on the application.

FYI, I forwarded the info from this thread to the Shell's perf team to see
if we are doing testing on dual procs. I just love harassing those folks.

The latest Vista runs very well on my Core-Duo notebook. No
issues with performance, don't know if "Lightning Fast" sums it
up, but it's fast.

Two response;

The Intel Core Duo will still be slower due to the latencies introduced by
the cores continuing to use the Northbridge chip for internal I/O.

Intel Core Duo cores are independently powered due to the fact that they are
multicore, and not dual core. Intel does not manufacture dual cores. They
fuse two single core chips into a single die. Only one core and one L2 cache
can use the Northbridge per clock cycle, because they do not have a crossbar
for internal communications ala AMD. Intel chips continue to use the same
old tired motherboard architecture they have had for 8 years.

One only has to look beyond the smoke that Intel produces, read the head to
head tests, and the superior technology will be readily apparent.

If you would look at the issue with an open mind, you would see that Intel
has an inferior design, and until it begins to build processors that are not
tied to a Northbridge FSB, they will continue to lag behind....

I have nothing against AMD. In fact I use AMD Duron 1300 at work
and Sempron 32 2600+ at home. (The last Intel was 350 Pentium II).
IMHO for desktop PCs AMD CPUs are in most cases more suitable.
For laptops I'm not so sure...

Anyhow, I plan that my next CPU purchase will be 64-bit dual-dore
processor with virtualization support ("Ring -1"):

Do you know if AMD will release such CPU with 939 socket?

Long story - around Christmas was shopping a new notebook. 1st
choice, Toshiba Satellite ( Bad ! - Drive way too hot). After a couple
of months of testing I opted for the Sony Vaio VGN-550. Decided
to go ahead and get a Core-Duo unit to get a little longer life-cycle.
So far, not disappointed with any aspect of it. Ships with 1.0 Gig of
RAM and may eventually take it up to the full 2.0 Gig capability. An
all-around good choice. However, for serious gaming it would be
better to go with their SZ series that has dedicated video GPU and
not the Intel 945 chipset based video. I could write an article about
the "Search" for the notebook - must have looked at more than 60+
models from most all the major vendors. Took a USB thumb drive
around to all the Retail stores to run tests on them. No store told me
to quit, but Circuit City wasn't too happy about me going from PC
to PC and making notes. Had more than a few customers who where
watching and asked for some advice based on my testing. Temps are
a big consideration for me and the Vaio stays nice & cool, even under
some heavy loading.

The new crop of AM2 and S1 procs will support Pacifica, which is a better
virtualization than the Intel scheme.
