Optimize the read-ahead file settings, speed up

The previous article "Catch the contents of the Prefetch read-ahead file in Win7/Vista/XP" must have been read by many people, so whether you think of it, these read-ahead files There is also a file read-ahead that needs to be loaded when the system is booted, and a pre-read that is loaded by the application. Can we make an article in this regard?

From the XP era, there are similar technical articles on the Internet. Let's revisit today and see how users under Win7 and Vista can optimize the speed of the switch.

As for the Windows operating system switching machine optimization, there will be a super big article out, more than the same year that was published in the Vista home. Of course, all the things are technical discussions, everyone dialectically Go and see, after all, it is mixed with some personal opinions of soft media editing. Take the essence, go to the dregs :)

Let's start with the topic of this article, how to speed up the on/off of the Win7/Vista/XP system by optimizing the read-ahead file settings. Here, considering XP, Vista and Win7 and all users under Win2003 and Win2008, we choose to use Rubik's cube as an example. Of course, the Vista system uses Vista optimization master, Win7 system with Windows7 optimization master is also a good choice.

First, the pre-reading program is prohibited from generating index files

The pre-reading file may cause the system to start slowing down because it is caused by reading the index file generated when the program is run. Therefore, we only need to ban the generation of those PF files.

Open the Rubik's Cube, click on “System Optimization" "Service Optimization" "Service Optimization" "Superfetch” This service and tick it, click Stop below and set it to manual, OK, so that it is comprehensive The Superfetch service is forbidden. The service name under the XP system is Prefetch. Please pay attention to it.

Second, only read system files

In fact, in the article "Catch the contents of Prefetch read-ahead files in Win7/Vista/XP" Mention that it is best not to turn off this prefetch service, we can choose to set it instead of all.

Since Prefetch saves the index information of the system and application, from the perspective of improving the startup speed, it reminds everyone that only the system file can be set to read, and the index file reading process of the application is skipped.

For this, we can run “regedit” after opening the registry editor, select

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager/Memory Management/PrefetchParameters

Double-click on the right side of "EnablePrefetcher", you can see that the value is 3, that is, read system files and applications, we can change it to 2, that is, only pre-read Windows system files. In this way, the Windows system only pre-reads the system files after it is started again.

Third, shut down automatically clear the pre-read file
