“ We believe that we can control the idle CPU usage of Windows 7 below 1%. "Mike Angiulo, general manager of the Windows Planning and PC Ecosystem team, said at WinHEC. What technology can Microsoft use to get Windows 7 to this level? For the Windows 7 pre-beta version, everyone's comment is: the speed has indeed improved a lot. However, it still has many potential obstacles. Improving performance and performance is still an important goal of Windows 7, and the hardware consumption problem is still to be solved.
Startup Speed Improvements
A big goal for Microsoft is to improve startup speed in Windows 7, rather than slow startup speed like Vista. The biggest problem in this part is the driver loading problem. Vista load drivers are run one after the other, and Windows 7 will load device drivers in parallel.
The second thing that needs improvement is the preloading service issue. Windows 7 only loads the services of the core group when it starts, and starts other services when needed. By reducing the number of startup services, users will get a better startup experience. A similar method is also used during the shutdown process. In Vista, it is usually seen that the shutdown interface has been paused for a long time or some programs cannot be quit. The programs or services that cannot be closed normally in Windows 7 will only call one service, as long as the service is turned off. Service can be.
Of course, the speed of startup is still related to the actual situation, such as the number of boot preloaded software, and software startup performance, which can only be solved by independent software developers themselves.
Hardware Problems
On WinHEC, Mike Angiulo has shown a comparison of Windows 7 and Vista memory consumption. Due to the improvement of the memory manager in Windows 7, the memory usage is independent of the number of open windows, and the management of these windows is performed by the graphics card.
The health of Windows 7 must also be supported by hardware vendors to provide a stable driver. Mike Angiulo said that most of the compatibility problems in the new system came from the problem of driver inspection. Perhaps some drivers will prompt: the driver can only be installed under XP, and even can not be installed. In this regard, Mike Angiulo said: "We will do compatibility work, please believe us! ”
