Fast horse whip, 20 seconds into Windows XP

The processing speed of the CPU in the computer is leaps and bounds under the command of Moore's Law. However, we found that the startup speed of the computer has not improved. From the pressing of the power button to the icon on the right side of the WinXP taskbar, it is generally displayed. More than 40 seconds. This is really dwarfed by the fact that the TV can hear the sound and see the image when the switch is pressed. First, the hardware factors affecting the startup speed The author through practice, found that the main components affecting the computer startup speed are the motherboard and hard disk, but not much relationship with the CPU. That is to say, under the same conditions, the expensive Pentium 4 computer and the cheap Celeron 4 start at the same speed. The motherboard is a "base" of various computer accessories, and there are many tasks to be done at boot time, such as self-test, search for various ports, and various external devices. Therefore, reducing the self-test time, reducing external equipment, and improving efficiency can increase the startup speed. If the computer is connected to a peripheral such as a scanner or a USB hard disk, it may slow down the system. It is recommended that you connect these peripherals when you need them. USB devices can be connected after booting. If the network card is not properly set, it will obviously slow down the system startup speed. If your computer does not need a network card, then directly unplug the PCI network card, the integrated network card can be shielded by the BIOS, so as not to affect the startup speed. Many motherboards detect integrated network cards much faster than independent network cards. This is one of the reasons why some computers have been able to access the Internet after more than a minute. The main factor determining the performance of the motherboard is the motherboard chipset. The main factor determining the startup speed is the disk performance and driver performance of the motherboard chipset. At present, the main brands of motherboard chipset are Intel, SiS, VIA, ATi, nVIDIA, and the best disk performance is Intel and SiS. Intel is an IT giant, and there is no one in the IT industry. It accounts for more than 60% of the motherboard chipset market share. The popularity of SiS is low, and the market share of motherboard chipsets is less than 10%. This may be related to insufficient publicity. However, on the AMD platform, its disk performance is the best and the price is the cheapest. In order to reduce the boot self-test time, some motherboard manufacturers will do some special design, which can shorten the BIOS self-test time to 5 seconds. We can choose different motherboard manufacturers according to their own needs, instead of listening to the dealer's recommendation. In addition to the power-on self-test, the computer startup time is mainly used to read system files from the hard disk. The hard disk works by reading and writing data on a high-speed rotating disk by moving the head (Figure 1). Then the higher the disk speed, the more data the head reads per unit time, which is very beneficial for system startup. In addition, hard drives with fast seek times and large caches can also significantly increase boot time. Promising purchasers or DIYs can consider Western Digital's "Raptor" series of hard drives, which are tightly funded or can be selected by Hitachi's large cache hard drives, which often receive performance awards.
Computer is a high-tech product of “soft and hard”, accessory setting and system optimization are also indispensable weapons for starting speed.
