Windows8 system resource usage

Beijing on October 8 morning news, the latest Microsoft Windows8 Caozuojitong will support the tablet PC and the Internet, which means that the system can be very efficient use of memory. Microsoft announced the details of the system's memory management on the official Building Windows 8 blog on Friday.

Insiders tested the Windows 8 system on a low-end Dell Inspiron E1505 notebook with 1GB of RAM and Intel T24001.83GHz processor. Windows 8 starts faster than Windows 7.

Microsoft acknowledges that many users will get Windows 8 by upgrading Windows 7 and older versions of Windows, so Microsoft wants to ensure that Windows 8 runs stably on older hardware devices. Microsoft has achieved this goal.

In the official blog, Microsoft compared the memory and CPU usage of the same 1GB memory computer running Windows 7 SP1 and Windeows 8 Developer Preview. The results show that Windows 8 consumes less system resources when idle. The Windows 8 Developer Preview has a CPU usage of 1% and a memory consumption of 281MB, while Windows7SP1 has a CPU usage of 5% and a memory consumption of 404MB.

Microsoft detailed the way to achieve this goal in the official blog. Microsoft uses a technology called "memory consolidation." With this technology, Windows will look at the system's memory usage, find out the code that runs for different reasons, but the same code, and then release the redundant code. In addition, Windows 8 also reduces the background service of the operating system and improves the way the background service works. This also makes the system performance significantly improved.

Surprisingly, the new Metro interface in Windows 8 is also good for memory usage. When a user uses a tablet, Windows 8 will not launch operating system components for the desktop. Not running these components can save 23MB of memory, and Microsoft will try to save more memory space in the future.

Microsoft has also used other techniques to reduce CPU and memory usage, including a smarter way to determine when to free memory and make memory usage more efficient.

The industry believes that this is a good trend, not only for Windows8. Microsoft may have realized that the future operating system should not be too large, but should be smaller and more portable.
