mechanism proposed by Microsoft to work with memory using a paging file turned out to be so effective that it is present on all operating systems Windows (Vindovs).At the time of the appearance he was in high demand.The main reason for this is the ability to run Vindovs applications demanding volume installed in the computer memory.Members, catching the era of Windows and DOS sunset, remember that on CD with DOS programs always specify the requirements for the configuration of the computer: type of video card, processor speed, the amount of free disk space and RAM.If memory has been less than required, the program does not start.This at a time when most computers installed Vindovs such requirements have a recommendatory nature (although there are rare exceptions, such as support for the correct version of DirectX).This was made possible thanks to the fact that the modern system uses the paging file.We can assume that this mechanism increases RAM.Imagine a situation where you want to run applications 2 GB of memory, and physically installed the module in 1GB.In such a situation, the system creates a Vindovs on the hard disk of special swap file (virtual memory), which will work as well as its physical counterpart.Of course, "the same" from the point of view of the user.
operating system Windows, is perhaps one of the most customizable.For it produced a huge amount of tweaking and optimizers with which the system can do almost everything, adjusting the parameters for their tasks.
Still settings "default" is not always possible to implement overt and covert features in full.Not paid attention to the swap file.The management of this system possible mechanism with built-in.The popularity of Windows 7 to access settings open the properties of "My Computer", following in the "System Settings", which open the tab "Performance."By selecting the "Advanced", you can set virtual memory.
Often on the forums to ask, "How to choose the size of the swap file?".The answer depends on the range of tasks (running applications) and the amount of installed RAM.There are many recommendations for setting up, but they are all based on the assumption that no swap file computer running faster.Computing power of modern computer systems are questioning this postulate.Quad-core processor and SATA-3 drive-based solid-state storage, more often occurring even in home systems, reduce the influence of the size of the paging file on the final performance.So, if the RAM is not less than 4 GB, you can try to disable swapping.Follow in the "Virtual Memory", remove the check mark, and automatic configuration tells Windows not to use this mechanism.It is recommended to reboot.If you have problems with the operation of applications will have to buy memory models, or even think about disabling the pagefile.
But off - this, of course, extreme.Sometimes it is possible to optimize the system operation, self-setting file size.This is indeed an effective way, reducing fragmentation.Select "Specify the size" and hocus-pocus: the initial size set to the maximum.Which one?You can follow the advice of Windows and hard-code a certain size automatically, but you can adjust in one direction or another.Best results are achieved with the installation of Windows on an empty partition and immediately (to install applications) specify the size of the swap.If the fragmentation of the file is missing, it's a little to improve the performance.As an option: to allocate a separate partition of the hard drive for swap, as is done in systems based on Linux.
