Leverage readyboost MB memory vista to enjoy the same performance

We all know that Windows Vista is a "food-consuming user". Microsoft's official website says that the minimum installation requirement for Windows Vista is MB memory. Experienced readers and friends know that the so-called minimum installation requirements often lead to a letter, for example, Microsoft once claimed that 64 MB of memory is enough to "marry" Windows XP, but in fact 64 MB is just enough to install. It is conceivable that if your computer is unfortunately "poor at home", it only has MB of memory, which means it is very difficult to be self-reliant on Windows Vista, let alone expect a smoother performance?

Medicine in gourd

You only need to prepare a USB flash drive without buying the memory (some computers cannot add the memory at will), you can enable the readyboost function, so as to bring our system performance to a higher level.

Many readers may wonder: Isn't it just a general USB flash disk? In my opinion, it's not as fast as a hard disk. How can it speed up the system?

I will talk about the medicines sold in the gourd of readyboost:

The data transmission rate, speed, cache capacity, and interface speed of the hard disk are greatly improved. The sequential access speed of the hard disk can reach 80 Mb/s, that is, it takes about 12.8 seconds to fill up 1 GB of memory. However, because the hard disk track time has not been improved for a long time, the random access speed of the hard disk can only reach 1 MB/second, that is to say, it takes about 1024 seconds to fill up 1 GB of memory!

For systems with small memory, hard disk performance is a bottleneck because data in memory is frequently exchanged with page files. For applicationsProgramIn most cases, sequential access speed is not important, but random access speed is the decisive factor, and hard disks suffer losses.

The USB flash disk has its advantages. The random access speed of the USB flash disk can be more than 10 times that of the hard disk. The readyboost function utilizes the high-speed random access capability of the USB flash disk to enable the USB flash disk as the superfetch cache for Windows Vista, so that Windows Vista with MB of memory can obtain better performance.

Note that superfetch is a new memory management mechanism introduced by Windows Vista. readyboost virtualizes a USB flash disk into a superfetch cache to improve system performance.

Practical drills

Although the principle of readyboost is complicated, the operation is simple. As long as you insert the USB flash drive into the USB interface, Windows Vista will immediately bring up an "automatic playback" dialog box. If the USB flash drive meets readyboost requirements, a "accelerate my system" option will appear, as shown in 1.
