Advantages of Dual-Xeon over P4 for a server?

Hi guys, when talking about just a small server, but one that is running quiet a few services, what are the advantages of dual-Xeon over P4. Say dual 2.0 GHz or 1.6 GHz Xeons vs. 3.0 GHz P4. Is there a significant improvement and in what areas? PLEASE do not comment on speeds, just answer the question asked. Also, when running multiple servers (software), is the system able to automatically determine which process runs on which CPU or does that have to be done manually?

[EDIT]
Wanted to ask something else, is it possible to run a dual-cpu motherboard with only one xeon? Like I can't afford two at the moment, will it be functional with only one?
 
I am running Dual Xeons on my Asus NCCH-DL board.

Dual chips can do better in a server enviroment as most task are very small and don;t require a lot of CPU power, just a CPU to do it. So in that case 2 slower chips will run as fast or faster then 1 High speed P4.

And yes you can run 1 cpu if you like.

Try to get at least a 2Ghz 533Mhz FSB 604Pin chip. Will have HT and be the northwood version of the Xeons.
Also take a good look at the Asus NCCH-DL board. It uses the 875 chipset but has a 64bit Southbridge. You can run Reg. ram, or ECC. It can be had for less then $249 now.
 
Then ones your talking about are Prestonia core right? What I'm thinking about doing is spending more money on a nice motherboard, at least a gig of ram and plenty of HDs. Only one CPU though - Intel Xeon 2.4 GHz 533MHz FSB, 512K Cache, Hyper Threading Technology ($225.00). Then after a month or two when I have some more money get a second one. So if that works it sounds like the thing to do.

Will definitely take a look at the Asus motherboards, been a long fan of theirs. The problem is that till now I've been looking at P4 server boards and asus makes none. Think I'm going to reconsider that. But keep the suggestions coming though 🙂
 
You can run a dual-CPU board with one CPU.

I don't understand why you ask for improvement areas but no comment on speed 🙂

You understand that you can only make use of two CPUs if you run multiple programs using CPU time at the same time or when you have multithreaded applications with several threads using CPU time and in an environment where userlevel threads they are distributed to OS level threads (not all do).

So what do you need to know?
