Signaling needs significantly more time in Mac OS X (Darwin) than on Linux. The processor plays a minor role: the Opteron at 2.4 GHz is a bit faster than the Xeon 3.6 GHz running exactly the same (x86) code. However, it is clear that the operating system plays a much bigger role: a 2.5 GHz G5 running Linux easily beats the identical system with a 2.7 GHz G5 running Mac OS X. Despite the FreeBSD heritage, the TCP signals are very slow (4 times slower!) on Mac OS X.

Why, I'm using it right now... :-)
MacOS10 uses FreeBSD code, but it is Mach at its core, a microkernel based OS. That might explain why the "TCP signals" are slower than Linux. Or it more likely be an example of your typical "poweruser" journalist type who doesn't have a clue what he's talking about except when it comes to things like leet case mods, high technology cooling for overclocking, blah, blah, blah...
That said, Linux on Opteron generally is much faster than OSX on G5 for server tasks. A lot of this has to do with the operating system design and optimization. It is widely known that massive server loads give less than stellar results on G5 servers. You can actually get better performance on the same hardware by switching to Linux PPC64. Apple has clearly optimized their operating system for desktop purposes rather than server purposes.

Yeah, but the gist of the article is that the problem is not the processor, but the OS. The implementation of Mac OS X made some fundamental design choices that will always make it slower for certain server operations.
That said, I have two Macs in front of me now and am responding to this on m dual 2 gig G5. The savings in time in never having to worry about viri, etc. more than outweighs any execution time penalty. I don't even turn on the PC with Windows 2000 server very often.
But I'll take Mac OS X over Windoze...
Let's see...
Linux vs. Linux...
Sorry. Don't care.
Heh, from one fedora user to another.

It seems that the old addage "breathe new life into your computer" carries the most weight on a mac.
I'm not sure. If the machine is still within warranty I'd get it replaced, if not just buy a new one and make sure the cartridges are the same so you can use your existing ones and save a little cash.
got a link?
Apparently you missed the list of contributors.
Or you just didn't read it altogether.........
^^^^^^^^^Here's to mactel next year! Bring it! We need it and the updates....... badly it seems.
Yeah, but the gist of the article is that the problem is not the processor, but the OS.^^^^^^^^^^^^^
That was precisely what I was saying. We need the updates. When mactel comes, we'll also get a new MacOS which should fix these problems.
^^^^^^^^^^^^^^The savings in time in never having to worry about viri, etc. more than outweighs any execution time penalty.^^^^^^^^^^^^^^^^
That's why I took windows off this machine about 2 years ago. But I've got the best of both worlds. It's kind of weird as I actually find myself wanting something to break just so I'll have something to fix.
And a new operating system every 6 months(roughly) is very nice.
Agreed.
I don't understand your comment.
I do and that's what is important.
The contributors didn't write the article.
