Check out the OSDL Data Center Linux project, as well as the Carrier Grade Linux projects.
Some good info about specific kernel changes can be found in the DCL Road Map.
OSDL has been *great* with regard to bringing companies and kernel hackers together on this subject. Gathering specs, performing QA, and allowing use of hardware. I had talked with Timothy Witham at Linux World about database performance, and he said he's seeing dramatic speed improvements on a 2.5 kernel over 2.4 (20%->30%, using standard TPC benchmarks). Though I don't remember the database he was using (not MySQL or Postgres, but it was open source I believe).
Performance in the data center isn't there yet for Linux. Almost nobody with a serious databasee will run it on Linux. Even though DB2 and Oracle run on Linux, it's just not as fast yet. 2.6 should hopefully change this, as the kernel developers have been taking suggestions in this area to heart.
Any type of file i/o or running more than about 4 apps just slows down the single processor too much.
FYI: Laptops tend to have much slower HDD's than desktops. This may cause more of a performance hit in this area...

and now i've been turned into a troll...
Yes, you have. Because you, and thousands of other whiney slashdot posters, can't take anything with a grain of salt. The Superbowl is a big American event. Watch it or don't. Either way, deal with it. I don't think Michael was really implying that you are Un-American for not watching.
I happen to like (American)football. I'm not a jock per se, but I do play sports.
At least right now what type of applications would this be good for? Do we really need that much storage? Perhaps if programmers wrote better code........... Then again remember when 2megs of memory was "the bomb" ?
*ahem* Fuck Off!
There. I just know everyone else was thinking that, and someone had to say it. I'm so incredibly sick of all these "why do we need anything better?" morons that I could just scream.
Sure, troll, flamebait, whatever. Just gotta release every-now-and-then!:-)
I would simply be happy if an *install* only required one CD. I remember fondly the days of putting a CD in, starting an install, and coming back later to have it finished (not asking for the next CD).

if the engine goes out in a rotary-wing, you've got maybe a minute to kiss your ass goodbye.
Not exactly true... Helicopters can 'glide' in a matter of speaking, but only if they start from an adequate height (about x-hundred feet or something). It's actually quite fascinating. I suggest looking it up (I don't know much about it, just that it's possible).
We use SPEWS. It reduces spam to 5% of before. It rocks.
If you turn off your mail server you can reduce spam to 0%! But how much *real* mail has been filtered? I think that is the reason many people are annoyed with SPEWS and the like. False positives IMHO are *much* worse than letting a bit more spam through...
This is exactly why my spam filters (spamassasin) don't delete my suspected spam, just move them to a separate folder that I check occasionally. You can never be *sure* that your filter(s) are working perfectly.
I play games for entertainment, coolness, sex appeal, geek factor, etc., but I don't wish to spend an hour tweaking stuff just right so I can play on GNU/Linux.
Some of us don't have Windows machines and need to wait for the GNU/Linux version to be able to play it.

Somehow I don't think making a screensaver do something cool across the network is a resourceful use of time.
Bah!
Mebbe students could do it as a project for a networking class? Perhaps it could be done to stress-test the network?
Once the code is opened, others may bring it further! It may not be incredibly useful, but no less useful than a normal screen saver!
Personally I'd like to see a screen-saver that bounces a ball between multiple machines. It would just be nifty. Like all the other screen-savers in the world.
Wow, so far most of the posts have been "why would you do this? It's not necessary."
Gawd, have things gotten sooo bad that coding useless but nifty apps is a lost art? Doesn't anybody tinker anymore?
I'm *soooo* sick of seeing post after post of "but why would I need this?" If you're asking this question, click the frigging back button already. You don't. Fuck off. Let the rest of us who would like a nifty-but-useless little app be merry.
I'm so worked up now I may write something like this just to piss off the 'practical'/. crowd...
While MS may maintain backwards compatibility, it only goes so far. Try using Win98 on a Win2k network. Not gonna work.
And remember: The spec is not only changing, it is also *hidden from sight*! The SAMBA team does *not* have access to it at all. I don't know about you, but packet sniffing for a few hours just to figure out how a simple login works doesn't sound like an easy task to me.
There are many reasons why SAMBA should fail, the fact that it is kept as close to the current CIFS implementation (as dictated by MS) as it is, is nothing short of amazing.
What makes you think that children are 'more mature' at the same age than we were? Just because you treat them as such, doesn't mean they are physiologically different. Children still mature at the same rate today as they did hundreds (thousands?) of years ago.
If your kid hunts down bondage bimbo with barb wire bra sites, guess what, your sheltering isn't working anyway, obviously he/she has handled that subject already whether you feel they are mentally prepared for it or not.
Since when are children able to make these decisions? There are reasons parents must guide children as they grow older, and why *most* parents won't purchase biker porn for their children. Children don't yet have a concept of right and wrong, and while they are learning those concepts, they must be guided, restricted, and punished for doing wrong.
Let children be naive for at least a little while, before adult-hood ruins it for them. Mr. Rogers (childrens program in U.S.) is much better for todlers than, say, the evening news. They don't yet have to deal with the problems of the world. Christ, they are still dealing with tying their shoes!
Yes, I too gave up the fun filled days of my youth for a narrow-minded leave me the hell alone attitude. I also used to watch the Learning Channel, but have since gave that up as it was just a bunch of useless learning. Who needs that? I grew up long ago and promptly stopped learning or accepting new ideas.

Not all computers are used for desktop applications. This probably fills some niche for small hardware, adequate speed (kiosks come to mind).
