Teach you a trick to speed up your Windows XP

Once the Microsoft Windows XP operating system was launched, it moved the vast majority of computer users with an aesthetically pleasing interface, coupled with outstanding overall performance (including a significant reduction in startup and continued use, and rapid application response), Allows many users to upgrade their operating system to Windows XP, a good experience of the addiction. However, in the use of the process, people found that the interface is indeed a lot of beautiful, but the performance does not seem so satisfactory. Why?

Microsoft has already stated before Windows XP that Windows XP does not require the use of state-of-the-art processors, but at least there should be more than Mhz,pentium II-level processors to perform better performance; In memory, 64MB is Windows XP runs minimum memory requirements, while 128MB is the minimum operating environment recommended by Windows XP. Of course, if there is more than 128MB of memory, that's certainly a good thing, but by contrast, adding memory from 64MB to 128M, and adding more memory on 128MB basis, will see a smaller performance gap and largely more dependent on workloads-which is like looking for " Inflection point of the curve ", the gain from adding additional memory capacity after an inflection point is relatively lower--for most workloads, the inflection point is between 64MB and 128MB. (Editor's note: Tests in the personal computer lab show that for most business applications, the upgrade of memory from 128MB to 256MB also brings significant performance improvements to Windows XP, but beyond 512MB, performance increases are not noticeable unless you perform an image processing operation.) Therefore, users should understand the hardware situation before upgrading the operating system to Windows XP to meet the above requirements, do not blindly start, otherwise will not achieve the expected effect.

With the hardware meeting the basic requirements, there are several ways to improve the efficiency of Windows XP.

A new installation of Windows XP typically provides better performance than an upgraded installation because it allows more control over the location of file and file metadata on disk. That is, in the process of installing Windows XP, you can dynamically determine the code and data that is needed to start up and optimize the location of the files on disk, depending on the configuration of your computer. When the computer starts, Windows XP can emit a large number of I/O requests that can be effectively handled at higher throughput, and the best time to make these requests is found, and these requests are interleaved in the device detection and initialization phase. This is done in a way that does not increase the overall startup time, thus significantly reducing the time required for the system to boot. During a new installation, it typically takes three reboots to perform this quick-start observation and optimization.

Increase system partition capacity, use high speed hard disk

According to Microsoft, Windows XP itself requires 1.5GB of hard disk space, plus the capacity of applications such as Office, the total capacity of the system partition should be 4GB to 8GB more appropriate (depending on the number of application software). Windows XP, like previous versions of Windows, uses virtual memory technology (see Figure 1), which means that when a computer is working, it divides a space on the system partition to be used as an extended memory to compensate for the lack of physical memory. This space is usually dozens of to hundreds of megabytes, the user can also be set to change the virtual memory file on other partitions (although it is recommended that the system partition is best) or to adjust the size of the disk space it occupies, but in any case it will take up a part of the hard disk storage space, In particular, when using large application software and the physical memory capacity is relatively small, the capacity of virtual memory files will be greater. Therefore, you should leave the system partition with enough space to allow the user to increase the capacity of the system partition when upgrading the operating system to Windows XP.

Make the hardware settings.

This problem includes the BIOS settings that are commonly mentioned. If let HDD-0 as the first boot device, open DMA mode, allow fast memory self-test, boot do not detect floppy drive, these settings can be to varying degrees to speed up the computer's startup and running speed, related articles more, here no longer detailed. The special emphasis here is on the jumper selection problem for the optical drive-which is especially important for computers that use two data lines to connect hard drives and optical drives, respectively. Today's popular hard drive and motherboard IDE interfaces both support DMA100 transfer mode, so the 80-wire data transmission line is generally used to connect the hard disk to the motherboard's primary IDE interface. Most of the optical drives only support DMA33 or PIO transfer mode, so the optical drive is usually connected to the secondary IDE connector on the motherboard using a 40-wire data cable. The default setting for the optical drive factory jumper is slave, so it occupies the secondary slave interface, which makes secondary master have no devices so that it takes a long time for the computer self-test and the operating system to start to detect secondary Master devices, and they don't get a response to waste a lot of time. So you should change the optical drive jumper to master, let it occupy the secondary master interface, and let the secondary slave interface empty, which can effectively shorten the system boot time 10-15 seconds. This method is tested by the author in all of Microsoft's operating systems will work.
