System resource usage of Windows 8
Beijing time on the morning of October 8 news, Microsoft's latest Windows8 operating system will support tablets and netbooks, which means that the system can use memory very efficiently. Microsoft announced the details of the system's memory management on its official Building Windows 8 blog on Friday.
Insiders tested the Windows 8 system on a low-end Dell Inspiron E1505 notebook, which uses 1GB of memory and an Intel T24001.83GHz processor. Compared with Windows7, Windows8 starts faster.
Microsoft admits 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 computers with the same 1GB of memory when running Windows 7 SP1 and Windeows 8 developer preview versions. The results show that Windows 8 consumes less system resources when idle. The Windows 8 Developer Preview version has a CPU usage of 1% and a memory consumption of 281MB, while Windows 7 SP1 has a CPU usage of 5% and a memory consumption of 404MB.
Microsoft detailed how this is achieved in an official blog post. Microsoft uses a technology called "memory merging." Through this technology, Windows will look at the system's memory usage, identify the same code that is running for different reasons, and then release the redundant code. In addition, Windows 8 also reduces the background services of the operating system and improves the way background services run. This also significantly improves system performance.
Surprisingly, the new Metro interface in Windows 8 also benefits memory usage. When users use tablets, Windows 8 will not start the operating system components for desktop computers. Not running these components can currently save 23MB of memory space, and Microsoft will try to save more memory space in the future.
Microsoft also uses a number of other techniques to reduce CPU and memory usage, including a smarter way to determine when to release memory so that memory is used more efficiently.
Industry insiders believe that this is a good trend and is not only beneficial to Windows 8. Microsoft may have realized that future operating systems should not be too bulky, but should be smaller and more portable.
