How much of that is hardware vs. operating system?

Windows has its problems, but you can't blame it all on the OS. A fresh install of Windows XP on a 10 year old machine won't perform as well as it did 10 years ago because it's expected to do a lot more than it did 10 years ago.

There's kind of an obligation to keep an antivirus running on a network-connected Windows machine, especially a server. AVG used to run reasonably in 64 megs. Now it won't even try to run in 512. Their full-download exe's have more than quadrupled in size in 5 years. And that's one of the less demanding AV's. I can't even imagine what Mcaffee and Norton require these days.

On top of that, much new software will force you to install otherwise-nonessential updates just to function. The smart ones bundle many with them, so they don't even need to ask ( I think this may account for some of AVG's increasing girth ).

So I don't think it's the Windows operating system that's ultimately to blame as much as the Windows software model. There's still people using Visual Studio 6.0, buggy and old as it is, because anything newer adds an entire .Net requirement to any program containing "int main()". If you build your software with MS tools, it will demand not just newer systems, but more runtime software in general.

There's no such continuous push to extend your operating environment in UNIX. Security fixes are one thing, but your distributor's not likely to suddenly decide they really, really like a newfangled language and insist on using it for everything, dragging along its hundreds of megs of footprint, memory-hungry daemon+runtime optimizer+JIT compiler, and endless updates just to do what used to work without it. Usually. (Looking at you, Java. ;p)

Furthermore, it really does matter what you intend to do with the server. I ran a web and database server with a good number of decently intensive sites on it for several years using an old Pentium III 866Mhz with 512M RAM, with the load average mostly below .1. One instance of Wordpress took more CPU and resources than everything else combined. It's keeping the improved 3Ghz machine at a load of .4 even now.

findsmb

FINDSMB(1)							   User Commands							FINDSMB(1)

NAME

       findsmb - list info about machines that respond to SMB name queries on a subnet

SYNOPSIS

       findsmb [subnet broadcast address]

DESCRIPTION

       This perl script is part of the samba(7) suite.

       findsmb is a perl script that prints out several pieces of information about machines on a subnet that respond to SMB name query requests.
       It uses nmblookup(1) and smbclient(1) to obtain this information.

OPTIONS

       -r
	   Controls whether findsmb takes bugs in Windows95 into account when trying to find a Netbios name registered of the remote machine. This
	   option is disabled by default because it is specific to Windows 95 and Windows 95 machines only. If set, nmblookup(1) will be called
	   with -B option.

       subnet broadcast address
	   Without this option, findsmb will probe the subnet of the machine where findsmb(1) is run. This value is passed to nmblookup(1) as part
	   of the -B option.

EXAMPLES

       The output of findsmb lists the following information for all machines that respond to the initial nmblookup for any name: IP address,
       NetBIOS name, Workgroup name, operating system, and SMB server version.

       There will be a '+' in front of the workgroup name for machines that are local master browsers for that workgroup. There will be an '*' in
       front of the workgroup name for machines that are the domain master browser for that workgroup. Machines that are running Windows for
       Workgroups, Windows 95 or Windows 98 will not show any information about the operating system or server version.

       The command with -r option must be run on a system without nmbd(8) running. If nmbd is running on the system, you will only get the IP
       address and the DNS name of the machine. To get proper responses from Windows 95 and Windows 98 machines, the command must be run as root
       and with -r option on a machine without nmbd running.

       For example, running findsmb without -r option set would yield output similar to the following

AUTHOR

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.

       The original Samba man pages were written by Karl Auer. The man page sources were converted to YODL format (another excellent piece of Open
       Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba 2.0 release by Jeremy Allison. The conversion to
       DocBook for Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander Bokovoy.
