Superfetch and is not a new technology, in vista age will have toshiba satellite a205 laptop keyboard started to use, but in view of the number of vista used less, but XP era of all kinds of computer skills always also thorough popular feeling, so a lot of people are in doubt why windows7 memory occupancy so big.
 
Superfetch memory management mechanism will users may use application page using memory space available for preload; As far as possible, avoid system occurs from hard disk page call; Let the application the fastest speed open; Not because of the computer for a long time and make use of idle suddenly become slow response, In the exit large application will be active to forced to transfer to the virtual memory before the page of memory to call. This seems to be a little to look professional, so then look down, and I will be very good for these characteristics of understanding.
 
Why first start-up procedure will feel very slow?
 
Believe that everyone had the similar experience. When I after startup, the toshiba satellite a205 series laptop keyboard first run a program, they say Word it, may need to 5 seconds to start. When I shut down after the open, perhaps for 2 seconds. If I don't close, directly open another Word documents, then the faster.
 
This is what reason is caused?
 
When we after startup, working set there is no Word the employees (page), he also at home (hard disk) inside. So when I call him, it from home to office (working set). This process is called do hard paging, of course need a long time. And when we close the Word, he was sent to the building's another room, but I again immediately call him, at this time, another room data has not been clear, he is not coming from home, but directly from data structure in the introduction. In not close the program under the condition of the Word, he doesn't need to make way for other applications, it also exists in office (working set) surface, summon him will be faster. This need not from toshiba satellite a205 s5801 laptop keyboard the hard drive to call in the data, but the data structure of the page to mount to work centralized process, it is called soft pages. Everyone knows that memory speed far more quickly than in hard disk, so soft paging use is the second operation procedure become quickly reason.
 
Windows 7 memory occupancy reasons
 
Now we know that when memory is need to program page can make the program startup faster and faster. And the Windows 7 Superfetch has the function of learning, since the first time use Windows 7, Superfetch began to record our usage, we often use the program page in the boot after loading in advance, then when we first open the program can get like the second open the same speed. So the preloading page will make our memory occupancy to grow. Say simply is to make all program operation in memory, avoid using hard disk hard paging space, this is what feeling for Windows and take up the cause of the great memory.
 
Check preloading memory
 
And in XP era, maybe you have also had the similar experience: when started toshiba satellite a205 s5803 laptop keyboard to use some of the program, because something left. Back when it found the system response is very slow, especially bad. This is because the XP memory management mode efficiency is very low.
 
When we left, and the program are in do not use state. At this moment the system some background program, such as disk sorting, antivirus software program will run at full speed, cause we use of some of the procedures page had to be pushed into a hard disk virtual memory. But when these background program after completion of a mission, XP system will not be pushed into before the virtual memory page guide back to memory. Then again in using computer, the system will helter skelter on temporary regulations, and even hard paging. Lead to program response extremely slow. So it looks XP free memory a lot of, in fact, didn't have any too big effect.
 
Windows 7 use advice
 
Anyone hope that through the optimization means let own computer speed to achieve the most ideal state, and memory effect is computer speed very important factors, we learned about the Windows 7 memory management mechanism, and then introduce what method can give system accelerated.
 
1, use more dormancy and sleep
 
SuperFetch due to the boot after preloading, so I suggest you do not shutdown. Try toshiba satellite a205 s5804 laptop keyboard to use dormancy or sleep, so the SuperFetch preload content will be retained. To improve the speed and efficiency.
 
2, use ReadyBoost
 
Many users from XP rose due to the system memory is not big enough, so I can't fully play the function of the SuperFetch. We can use ReadyBoost function to help us solve this difficult problem.
 
As long as meet the conditions of the usb flash disk can accelerate our system. toshiba satellite a205 s5805 laptop keyboard ReadyBoost function is the use of usb flash disk capacity as SuperFetch preload page storage space. But because of the special micro soft algorithm, so will not affect the life of the flash. And, for the best ReadyBoost flash for physical memory size 1 ~ 2.5 times. If the system of physical memory is large enough, there is no need to use the ReadyBoost. Right click the U disk plate operator choose attribute, switch to readyboost column, speed up to the standard of the U disk can open this function.
 
Not all U disk can use
 
Through the SuperFetch understanding, hope more friends come into use windows7 toshiba satellite a205 s5821 laptop keyboard team. In fact the same for the Windows, different and where? Not accustomed to also is temporary. After all, after a Vista of temper, Windows 7 will become more mature!
