Playing Music in Vista Drags Down Network Performance

[Husar]

Well, duh - it's webradio, so of course that one thing using the network will use up bandwidth from the other application's bandwidth... but the complaint was about multimedia and network, not about network and network.

I know, it was some sort of bad joke, I'm sorry you can't expect much better from me.

That said, I'll address your other issues, even though, again, I'm not sure how they are relevant to the topic.

They're actually things I read about and which concern me to some degree. I wonder why Vista runs fine only on quad cores when it's very likely that we will see eight cores in the (near) future. also makes me wonder at how many cores XP will stop getting optimal performance out of them. It was just relevant to show that I have my criticisms as well before anyone thinks that I'm drroling everytime I see a windows logo.

Then run it on 32 bit systems!
Again, I realise you're being tongue-in-cheek (at least I hope you are), but I'm not sure what point you're trying to make (unless, like I said above, you're trying to invalidate all criticisms by showing some obvious non-issues).

I brought that one up before and I meant that if the programs were programmed in 64 bit, they might be faster. Supreme Commander for example lags a lot even on my dual core, maybe if I were lucky, it wouldn't lag as much if it were programmed in 64bit, but then I'm not an expert on these matters. If a 64bit mode could be made optional like DX10 or so, or maybe choose a version upon installation, that might help with some games.

I don't know what Vista does, but the first part is incorrect. First of all, OSes do recognize 4GB as 4GB. They can also support a lot more memory - have a look at any of the "-bigmem" linux kernels, guess what the "bigmem" allows them to do ? Here's the output from top on a machine I'm connected to, I bolded out the relevant part.

Well, I just repeated what some random guy on another forum said, apparently Windows in 32bit only supports 3GB RAM. I read about something like that from a more knowledgeable source before but don't remember what was said. for all I know that guy could just have a malfunctioning RAM stick.

The part about 4GB vs 3GB _may be_ related to the following issue (Note: this is the case for linux, I don't know about windows, but my guess is that it is a similar issue): on 32 bit systems, there is a limit of 4GB for _one process_. One process cannot access more than 4GB of memory - theoretically. The practical limit, however, is about 3GB for linux, 1Gb out of those 4GB being reserved for the kernel. This limit can be raised by hacking the kernel, up to 3.7GB, from what I've read.

According to memtest, the limit in XP 32bit is somewhere around 8xxMB, the program told me to start another memtest to test the other parts of my RAM. Made me wonder how games use more RAM then, but I never bothered to find out.

I'm not a Linux expert and currently I'm too lazy to become one since my Vista is still running fine.

Nah, it's okay, if you were kidding it's all right, except that as you know sometimes it's kinda hard to tell when someone is serious and when they're joking on these internets.
It's all good though.

Don't drool! The ladies don't like it!
I think the main reason is that it is very hard to optimize something for an architecture that doesn't exist yet.
Yes, people use simulators, but simulators, as their name suggests, are just simulators - and they are not always realistic enough, or the final product may be different from whatever flavour of simulator people were using at a given point in time.
Take for example the SMT technology (Intel's Hyperthreading), which was much of a flop, imo (do you hear anything about Hyperthreading from Intel these days ?). They played with the architecture on simulators quite a bit before making the product, and it looked good on paper... Then they built it... and it was far from getting 30% more performance as marketing figures claimed.

That's what I think is the main reason...

Another reason for that is another pretty hot topic in the research community - how do we manage all these cores ? How do we write software for them ? Do we need new programming languages ? New parallel programming paradigms ? How do we easily make old software run better (i.e., take advantage of the extra resources) on them ?
Lots and lots of problems, and no definite answers yet.

Hope this sheds a bit more light into your questions.

I don't think 64bit has anything to do with running faster, it's just addressing some address (pardon the pun) limitations, mainly, afaik.

Maybe the thread title should be just "Vista Drags Down Network Performance."

What an awful OS.

FWIW, there's finally a decent technical explanation of what's going on.

Wow... so basically they're saying that even with the quantum leaps forward in hardware over recent years, Microsoft couldn't manage to code an OS that can handle LAN traffic and playing a song at the same time without bogging down the CPU? That's crazy.

Really, how bloated and inefficient can you get?

My favorite line from the article: At this point, it becomes clear that the process scheduler folks and the networking folks are bitter enemies and do not converse.

-edit-

Everybody knows that starting with Windows NT, Microsoft copied the networking stack from BSD Unix. Bad form, poor sportsmanship and all that, but it meant that the networking was pretty stable. I remember reading that Microsoft was throwing out the entire networking stack and re-writing it from scratch for Vista. And I remember thinking, "Hmm, that could go badly."

At least with a pirated clone of Unix, it worked as advertised. Reading about the shivs and hacks needed to square the circle in Vista makes my eyeballs ache.

Well, I always say, better a good copy than a bad new invention. But people always complain about good copies for some reason.
The Chinese government runs a whole country based on good copies.
