Every time you run a program, open multiple windows, you will find that the computer is going to read and write operations on the hard disk madly. Sometimes even the shutdown program is unbearable, even if you have more than 64M of memory. At this time, you should optimize your system.
First, remove the taskbar "junk" daemon
take a look at your current system resource availability: My Computer - & gt; Control Panel - & gt; system, select Performance By "system resources" you can see the current usage of your system. Just boot, before running any program, this percentage is more than 90% to show that your system optimization is quite good, not occupied by some background garbage programs.
If a machine, you are the percentage of less than 50%, then your system resources are wasted quite powerful. Open a few more windows, run a few programs, your system will enter and unstable state, it will take course to crash and automatically restart.
Although there are many system optimization software that can automatically optimize the system, but it generally requires direct operation of the registry, which inevitably has certain risks, and the system can no longer be started! If you want to learn something, let's do it yourself.
First look at the lower right corner of the task bar of the screen, there are several background tasks in the occupied system resources, and many of these programs is relatively small.
RealPlayer's StartCenter, Winamp's Agent, super king automatic diagnostic testing and other background programs while claiming to be faster start their own program, and provides automatic monitoring related functions to open files, but actual results and Not significant, but it takes up a lot of system resources. It is recommended to keep only some of the necessary background programs, such as firewalls, anti-virus walls, and so on. How
closing some have started a program but do not require it? First look at: Start -> Program -> Start, the things inside can basically be deleted, especially like some "Office Start", "File Search" and other special resources. Unless you want to run a program when the machine is started.
Many of the daemons in the taskbar are not started this way. To delete them, the registry is processed. The registry is an important place for the Windows system series to store system hardware and software configuration information. Improper operation can lead to catastrophic consequences. Fortunately, Windows itself provides an application that can perform safe operations on the project involved in startup, which is the "system configuration application." It can be started by: Start->Run, enter "msconfig", OK.
It can be seen that there are six labels of “General”, “Config.sys”, “Autoexec.bat”, “System.ini”, “Win.ini” and “Start”. The three tags that we are going to cover are "Config.sys", "Autoexec.bat", and "Startup". In fact, the items in Config.sys and Autoexec.bat can be unchecked, that is, all the hooks are removed.
Go to the "Startup" tab, where you can remove the checkmark in front of the project that is not relevant to normal operation. After confirmation, a reboot is required to take effect. Restart, and then look at the available resources of the system, is there a big change! Of course there are some special
daemon still can not be disposed of by this process. For example, RealPlayer's StartCenter, although you can remove the selection in the "Startup" tab, but will automatically join a row after restarting. To get rid of it, you need to configure it in its running program.
Second, improve the performance of
file system file system of the machine to a network server, so that Windows can use more physical memory for disk read-ahead (including CD-ROM). But Windows does not take up the memory required by its applications, but automatically adapts to the memory needs of various applications.
Specifically, the following: My Computer - & gt; Control Panel - & gt; system, select the Performance tab and click File System (file system) button to select Netowrk Sever (network server) from the drop-down list, Then confirm. After the restart, the setting will take effect.
three, OPEN file system DMA mode
This feature is a direct memory access (DMA, Direct Memory Access Abbreviation) for a hard disk and an optical disk drive to maximize system performance, because now The biggest bottleneck of a personal computer is on the input and output of the disk. DMA data on a PC can directly access the hard drive, but does not take up too much CPU time (compared to PIO mode), so that your CPU to perform other tasks,
Specifically, the following: My Computer -> Control Panel -> System, select the "Device Manager" tab, expand the hard disk controller or CDROM item, select the corresponding drive device in the expansion, click "Properties", then select "Settings" and select DMA checkbox, you can reboot after rebooting.
course, to use DMA mode, your CDROM and hard drive to support the corresponding function can. If your CDROM and hard drive are too old, you may not be able to enjoy the superiority of this feature.
Fourth, defragging
Windows9x series with the FAT file system, because the form of the linked table, at the beginning of each sector of the file is stored in a row, but with With more file creation, deletion, etc., newly created files are distributed over discrete disk sectors with sectors and/or empty sectors of other files distributed in the middle. As more file operations progress, the discrete empty sectors are more scattered, which is called disk fragmentation. It is not literally "the disk has a small physical fragment"! When
defragging is to move files and other treatment, so the file by sector stored in a row, the blank sector together, and reduce the file system read and write head movement, positioning time, thus improving file Read and write time.
though Windows also has a "Disk Defragmenter" to defragment the hard disk, but the algorithm of this procedure is quite stupid, only time-consuming finishing, and finishing later appeared fairly easy to provide a lot of disk fragmentation.
A number of third-party disk defragmentation tools, such as Norton's peed Disk, can be used, which is fast and efficient. It is also recommended to turn off any windows and background programs, such as anti-virus software, network firewall, etc. when defragmenting the disk. Because these daemons read and write to the disk from time to time. When the defragmenter detects that there is a disk read or write operation, it will restart the defragmentation.
After the above process, I believe your system has been a considerable degree of optimization, when then run some more big programs and open more windows, it is not perceived not the same as before!
