Microsoft is optimizing Windows 7 in order to increase performance, and, in this context, the dispatcher lock is one of the components that has got cut off . According to the Redmond company, fewer hardware locks are synonymous with boosted parallelism, namely a new level of efficiency when it comes down to taking advantage of modern processing architectures. This is valid for Windows Server 2008 R2, namely Windows 7 Server, and, naturally, also for the Windows 7 client, since the two operating systems share the same code base.
“With Windows 7, the dispatcher lock is replaced with several finer-grained synchronization techniques, thus effectively distributing resource contention. The main benefits for applications include increased system performance and more optimal use of available hardware resources,” Phil Pennington, Windows Server Technical Evangelism, revealed.
Evolving from Windows Vista, Windows 7 is embracing the many core CPU world, delivering the promise of enhanced performance through the advantage represented by parallel computing. However, in order for Win7 to be tailored to many core processors, the platform’s kernel had to be freed from past relics such as the dispatcher lock. Read More»

Jason Microsoft has shared bits and pieces of how it is adding new features to its development tools to better support parallel processing.
But the next release of Windows client and server also are going to incorporate changes designed to improve their parallel-processing support.
While Microsoft execs and those who’ve managed to get their hands on early builds of Windows 7 have focused largely on user-interface tweaks in Windows 7, there will be some under-the-covers changes, too. Microsoft officials have said on the record that deep-level changes between Windows Vista and Windows 7 will be kept to a minimum, in order to insure application and driver compatibility. Yet Microsoft officials acknowledge that Win32, the core of Windows, is not suited for asynchronous, concurrent computing.
Microsoft is taking the first steps toward remedying this limitation with Windows 7 and its joined-at-the-hip sibling, Windows 7 Server (the product currently known as Windows Server 2008 R2). Read More»

Laptops are complex little machines with a variety of configuration options which can lead to very confusing buying decisions. In this article, we are going to cover out factors that one should consider before purchasing a laptop. These 6 factors are the crux of any laptop purchase and by using these as a guideline, you can land the most appropriate mobile PC for your needs.
1- Weight
The lighter the laptop, the easier it is to move around. Prices usually have an inverse relationship with the weight of a laptop. Hence the lightest of laptops will almost (always) cost more than the heaviest ones.
Another relationship is the features of a laptop which would affect the weight of the laptop, which can be if it has a powerful graphics card, or a larger screen etc. The laptop will end up being comparatively heavier and more expensive. So keep a look out for that.
2- Power Consumption
Battery life is critical for users who are on the go. On an average workload, a regular low budget laptop would easily give you 2.5 to 3 hours of battery time. A fairly good machine would easily clock in 4 hours. Read More»

With many innovations being made to today’s PC’s hardware, laptops and desktops have become much smaller and lighter. But one drawback to that light weight convenience is heat.
Computers today can pack more processing power in a much smaller and denser space, if you don’t keep them cool, you can pretty much guarantee a hardware failure will occur.
Fortunately, there is an easy way to keep tabs on hardware temperature using a free utility called CPUID.
HWMonitor from CPUID software is a hardware monitoring program that reads your PC Systems main health sensors, such as voltages, temperatures and fans speed. I mostly use it on my home PC to keeps tabs just on temperature since I use a laptop. Read More»

The Windows Experience Index Score was introduced in Windows Vista and used to give you a good idea of the capabilities of a computer. You can use a computer’s Experience Index base or sub score to help determine if it’s what you need when purchasing a new computer.
The Experience Index Score rates your computer’s components performance from 1 to 5.9 with 1 being the worst performing and 5.9 being the best. The score’s benchmarks were established when Windows Vista was released.
Base Score Explained
The base score represents the overall performance of your system as a whole, based on the capabilities of different parts of your computer, including RAM, CPU, hard disk, general graphics performance on the desktop, and 3-D graphics capability. Read More»
