XP system optimization makes the performance better.

Every time you run a program, open multiple windows, you will find that the computer is going to read and write the hard disk madly. Sometimes even the shutdown program is unbearable, even if you have 64M or more. Memory. At this time, you should optimize your system. First, remove the "garbage" in the taskbar. The background program First look at the availability of your system's current resources: My Computer -> Control Panel -> System, select performance, by "system resources" can be seen The current use 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, your percentage is less than 50%, then your system resources are wasted a lot. 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 softwares that can automatically optimize the system, 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 taskbar at the bottom right of the screen. There are several background tasks that are consuming system resources, and many of these programs are used less. RealPlayer's StartCenter, Winamp Agent, Super Solution's automatic diagnostics and other background programs claim to speed up the startup speed of their own programs, and provide automatic monitoring of the related functions of opening files, but the actual use effect is not significant, but occupied 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 do I close some programs that are started and not needed? First look at: Start -> Program -> Start, the things inside can basically be deleted, especially like some "Office Startup", "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 projects involved in startup, that is, "system configuration use program". It can be started by: Start->Run, enter “msconfig”, OK. It can be seen that there are six tabs: "General", "Config.sys", "Autoexec.bat", "System.ini", "Win.ini" and “start” We also need to deal with the three tabs "Config.sys", "Autoexec.bat", and "Start". 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 from the 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, some special background programs can't be handled by this method. For example, RealPlayer's StartCenter, although you can remove the option in the "Start" folder, but will automatically join a line after restarting. To get rid of it, you need to configure it in its running program. Second, improve the performance of the file system Set the machine file system as a network server, which can make Windows use more memory for disk read-ahead (including CD). But Windows does not take up the memory required by its applications, but automatically adapts to the memory needs of various applications. Here's how: My Computer -> Control Panel -> System, select the Performance tab and click the File System button, select Netowrk Sever from the drop-down list, and then OK. After the restart, the setting will take effect. Third, open the file system DMA mode This feature is for the hard disk and optical drive direct memory access (DMA, Direct Memory Access abbreviation) to maximize system performance, because now the biggest bottleneck of the personal computer is on the disk input and output . DMA allows the PC to directly access the data on the hard drive, but does not take up too much CPU time (compared to PIO mode), so that your CPU can perform other tasks, as follows: 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 deployment, click "Attributes", then select "Settings" and select DMA checkbox, you can reboot after rebooting. Of course, to use DMA mode, your CDROM and hard drive must support the corresponding functions. If your CDROM and hard drive are too old, you may not be able to enjoy the superiority of this feature. Fourth, the defragmentation of the disk Windows9x series uses the FAT file system, because the form of the link table, in the beginning of the file, the various sectors of the file are stored continuously, but with the establishment of more files, delete, etc., newly established The 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"; Defragmenting the disk is to process the file and so on, so that the file is continuously stored in sectors, so that the blank sectors are grouped together, which reduces the time for the head to move and locate when the system reads and writes files, thereby improving the reading and writing time of the file. Although Windows also provides a "disk defragmenter" to defragment the disk, but the algorithm of this program is quite stupid, not only time-consuming, but also quite easy to appear after the disk fragmentation. Many 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 processing, I believe that your system has been optimized to a considerable extent, and when you run some large programs and open more windows, you are not aware that it is different from before!
