Solve the problem that the memory occupation is higher than that of the application process

Problem description ： The computer just turned on , The memory usage rate reaches 80% And above , The system manager shows that the memory consumption of the process is not high

The actual memory usage should be “ Resource monitor ” View in , The meaning of parameters is as follows ¹：

• Submit ： The system is required to reserve so much memory for the program , If not satisfied , The prompt box of insufficient memory will pop up .
• The working set ： It refers to how much it currently occupies , It is usually much more than what is displayed in the task manager , Here, the value of the working set is actually occupied .
• Can share ： When you open more and bigger software , Or when it comes to memory consolidation , This part will be distributed to other software .
• special ： That is, the program must run , Will not let out the memory .

The methods listed below will not immediately reduce memory consumption , Need to restart the computer . Methods are sorted in no order , Please use

Application of the methods listed in this paper

• Use software such as system manager to clean the memory , But the computer still uses too much memory
• The physical memory size of the computer （ Memory module capacity ） Close to the computer motherboard can bear the upper limit . Check the method

1. close nbu Network data monitoring

stay cmd Windows use commands sc config ndu start=disabled, Under the administrator's authority .
The reason is that the network data monitoring of the system conflicts with the data monitoring driven by the network card , As a result, the non page cache cannot be released ².

2. close SQLServer service

This operation applies to the previous Installed and used SQLserver database Users of . According to use SQLserver Different configurations of ,SQLserver The related processes often occupy at least a few G Of memory space , And this part of memory will not be temporarily released due to insufficient memory . So for short-term or long-term use SQLServer Users of the service , You can disable the corresponding service , In the future, if you use restart .
SQLServer There are many services , But you only need to shut down a few core services .

Turn off the above services and disable the above services as shown in the figure . Or in task management , see SQL server The service corresponding to the process , Then ban it .

3. close superFetch Super preview service

According to the email information returned by Microsoft engineers in Greater China ：win10 As soon as the power is turned on , Memory usage is too high , The main reason is because Win10 SuperFetch The problem of super preview service ：

“Windows10 Of SuperFetch Service is for Enterprise applications and large-scale collaboration software And designed , There is no need for individual users to turn on . Professional software used in large enterprises and enterprise strategy management , The database startup process will last for 10 minutes . And use SuperFetch, The start-up time can be reduced to 6 Within minutes, .
However, for individual users , The startup time of the daily software used in daily life is very short Usually in 1-2 In seconds , SuperFetch The acceleration at this time is just 0.2~0.5 second , Basically, it can be regarded as useless , And it will also increase the monitoring of hard disk ( Loss CPU Performance time ) And read time ( Add hard disk IO Addressing thread allocation ). and SuperFetch It is invalid for game programs , For individual users and gamers , Opening this service will only Intangible loss CPU Performance time and loss of hard disk IO Addressable thread performance .”

close SuperFetch There are two ways , One is to modify the registry , The other is through “ service ” close SuperFetch and TimeBroker Two services .
It should be noted that , yes , we have WIn10 Version disables passing “ service ” modify SuperFetch and TimeBroker Authority , Only use the registry to modify .
There are many tutorials on the Internet about how to turn off these two services through the registry , Here is one of the more detailed steps for reference . Click send

4. Update driver

From the first solution , We can know that excessive memory occupation may be related to memory overflow caused by driver occupation conflict , So you can update the computer driver , The new driver may provide corresponding solutions .

Here I use Master Lu's driver management to update the driver （ The main problem may be the network card driver ）.

5. Manage startup items

stay “ Task manager ” in “ start-up ” Check the program of system self startup in an item , Right click to enable or disable

6. Set up virtual memory

Virtual memory is Windows One of the solutions to the problem of insufficient memory . The principle is to use part of the hard disk of the computer as memory space . When memory runs out , The computer will automatically call the hard disk to act as memory . Virtual memory is often placed on the system disk C Plate , The file name is PageFile.sys.

It should be noted that , This method has high requirements for hard disk . Even if it's SSD, Its reading and writing speed is similar to RAM The gap is still wide , The effect of virtual memory on system hard disk 4K The requirements for performance and seek time are relatively high , When the virtual memory is set on the system hard disk , Average performance SSD There will be speed drop , Because when memory and hard disk exchange data , It will slow down the system .

because poor Computer SSD The relatively small , And the reading and writing speed is not fast enough , Therefore, this method is not used . Post here the Using blogs .

7. SSD cache

【 Reprint 】Win10 Memory usage is too high And it is inconsistent with the task manager

8. Windows Memory diagnostics restart

Use Windows Built in memory diagnostic tool , Usually, there is nothing wrong with the inspection wwww. But dead horses should be healed alive , This is the easiest way .

9. close Windows Quick start

Windows The principle of quick start

「 Quick start 」 Functions combine Windows 10 Intercooling shutdown and sleep function , Normal cold shutdown Windows Will close all applications and log off the user , All contents must be reloaded at the next startup . If enabled 「 Quick start 」 Options , When shutting down Windows 10 All current system states will be written to the sleep file , Then turn it off .
When you start the computer again ,Windwos There is no need to reload the system kernel 、 Driver and system status , Instead, it is loaded directly from the sleep file and flushed into memory , Push directly to users after completion Windwos Login screen . In this way, it can start quickly Windows 10, Save users a part of the startup waiting time .

As can be seen from the above definition , Fast startup has a certain impact on the memory occupation of boot , But from the perspective of personal practice , Turning on and off quick start has little effect on the memory occupation after startup . Instead, it reduces the user experience more .

How to close

1. win10 The task manager of displays the memory occupied , The reason why it takes less memory than it actually does ︎

2. sc config ndu start=disabled What does this command mean ？ What is the system default ?︎
