Windows 7 On Multicore — How Much Faster?
snydeq writes "InfoWorld's Andrew Binstock tests whether Windows 7's threading advances fulfill the promise of improved performance and energy reduction. He runs Windows XP Professional, Vista Ultimate, and Windows 7 Ultimate against Viewperf and Cinebench benchmarks using a Dell Precision T3500 workstation, the price-performance winner of an earlier roundup of Nehalem-based workstations. 'What might be surprising is that Windows 7's multithreading changes did not deliver more of a performance punch,' Binstock writes of the benchmarks, adding that the principal changes to Windows 7 multithreading consist of increased processor affinity, 'a wholly new mechanism that gets rid of the global locking concept and pushes the management of lock access down to the locked resources,' permitting Windows 7 to scale up to 256 processors without performance penalty, but delivering little performance gains for systems with only a few processors. 'Windows 7 performs several tricks to keep threads running on the same execution pipelines so that the underlying Nehalem processor can turn off transistors on lesser-used or inactive pipelines,' Binstock writes. 'The primary benefit of this feature is reduced energy consumption,' with Windows 7 requiring 17 percent less power to run than Windows XP or Vista."
heheh Nice troll here :)
I can't call that English
Can I run Snow Leopard on the computer I built myself?
I'm not going to buy a gay computer just so I can run a gay operating system.
I would tell you to suck it, but as an Apple using homosexual you probably already have a dick in your mouth.
Windows 7 is nothing but Refurbished Vista.. which was XP with lots of bloat and less of new features. The only reason Windows 7 is being released is for MS to make a revenue stream for nothing. It is not much different from XP.
If you keep throwing chairs, one day you'll break windows....
So, you're telling me that before Windows 7, the Windows kernel was still using global locks for this kind of purpose? Seriously?
I may be slightly mistaken about the timeframe, but wasn't that kind of thing fixed in the Linux kernel, like, at least 5-10 years ago? I remember reading some LWN articles about it ages ago, at least.
If so, I had no idea Windows development was *that* far behind the times, from a technological perspective.
Every expression is true, for a given value of 'true'
Where have you been for the past couple of years?
Slashdot's a Microsoft fansite now. Criticism of Win 7 or even just mentioning MS marketing means an automatic "Troll"mod.
The Windows drivers are using every setting of that motherboard, while the Linux drivers dont even know about some of them.
You only experience problems in Linux.
Could it maybe be that your Linux installation cannot cope with some of those settings, which it doesnt even know exist, being non-default?
Use your brain instead of your religion. The problem is on the Linux end. Nobody at all is getting paid to make sure that every advanced feature of your motherboard is leveraged under Linux, while there is surely a team of developers bring paid a very healthy salary to make sure that every feature can be leveraged under Windows.

The only way I would run Windows (anything) would be inside of VirtualBox on either a Mac or Ubuntu box. Given this scenario, how much would improved multi-threading matter?

And some of us have actually don't english learning. There
really isn't any reason the language should be getting in the way. The
bottlenecks should be all in your heads. A well built head..
Mac OS is for fags.
There's literally no rational reason to buy a Mac.
Only fanboys would even consider it.
The fanboy phenomenon is all there is to Apple's sales.
