Ethereum Alpaca can register

1.

Control the CPU utilization rate at 50 methods:

1, press and hold Ctrl + Alt + delete on the keyboard at the same time, and click "enable Task Manager (T)" to see the CPU utilization rate The CPU utilization rate here is not high, because the game is not running and many background programs are not opened.)

2. It is too laggy to see that CPU is used. If CPU is used to a certain extent, the computer will become stuck or even crash. Now CPU only uses 10%~15%. This is good news. When it comes to 100%, it will be worried.
CPU utilization is automatically allocated by the operating system according to the requirements of the application, and can not be intervened by indivials
the reason for the computer card is not the low CPU utilization. The lower the CPU utilization, the more idle the current system is, and the faster the system should respond
the reason for the computer card should be found from other aspects. It is likely to be caused by poisoning. It is recommended to check the anti-virus or reload the system
consider the system hardware problem again: please observe whether the indicator light of the host hard disk is on for a long time or flickers very frequently. If so, please use the hard disk detection tool hdtune to detect whether there is a problem with the hard disk.

3. If the system idle process takes up too much CPU, it is normal, because the higher the CPU, the better. You can look at the related articles. If you look at the situation where 100% CPU is frequently used, the main problems may occur in the following aspects:

nine possibilities with high CPU utilization rate

1. Anti virus software causes failure

since the new version of kV, Jinshan and Ruixing have joined in the random monitoring of web pages, plug-ins and e-mails, it undoubtedly increases the burden of the system. Treatment: there is basically no reasonable treatment, try to use the least monitoring services, or upgrade your hardware

2. The driver has not been certified, resulting in 100% CPU resource occupation

a large number of test version drivers flooding on the Internet, resulting in difficult to find fault causes. Processing method: pay special attention to the graphics card driver. It is recommended to use the driver certified by Microsoft or officially released, and strictly check the model and version

3. Viruses and Trojans cause a large number of worms to replicate rapidly in the system, resulting in a high CPU utilization rate. Solution: clean up the system memory and local hard disk thoroughly with reliable antivirus software, and open the system setting software to check whether there are abnormal startup programs. Update anti-virus software and firewall regularly, strengthen anti-virus awareness and master correct anti-virus knowledge

4. Control panel - management tools - Services - rising realtime monitor service. Right click to change to manual

5. Start - & gt; Run - & gt; msconfig-> Start, close unnecessary startup items, restart

6. View the "svchost" process

svchost. Exe is a core process of Windows XP system. Svchost.exe not only appears in Windows XP, but also exists in Windows system using NT kernel. Generally, in Windows 2000, the number of svchost.exe processes is two, while in Windows XP, the number of svchost.exe processes rises to four or more

7. View the network connection. Mainly network card

8. View network connections

when a computer with Windows XP installed as a server receives a connection request on port 445, it allocates memory and allocates a small amount of CPU resources to provide services for these connections. When the load is too heavy, CPU utilization may be too high, because there is an inherent trade-off between the number of work items and responsiveness. You need to determine the appropriate maxworkitems settings to improve system responsiveness. If the value is not set correctly, the responsiveness of the server may be affected, or a user monopolizes too many system resources

to solve this problem, we can modify the registry: expand [HKEY] in the registry editor in turn_ LOCAL_ MACHINE\ SYSTEM\ CurrentControlSet\ Services\ Branch, and create a new DWORD value named "maxworkitems" in the right window. Then double-click the value, type the following values in the open window and save to exit:

if the computer has more than 512MB of memory, type "1024"; If the computer memory is less than 512 MB, type 256

9. Let's see if using the right mouse button in Windows XP causes 100% CPU utilization.

recently, we reported that using the right mouse button in the resource manager will cause 100% CPU utilization. Let's see what happened

symptom:

in the resource manager, when you right-click a directory or a file, You may have the following problems:

any file operation will stop at that time, and the network connection speed will be significantly reced
all stream input / output operations, such as listening to music with Windows media player, may be caused by music distortion:
when you right-click a file or directory in the explorer When the shortcut menu is displayed, the CPU utilization will increase to 100%. When you close the shortcut menu, it will return to the normal level<

solution:

method 1: close "use transition effect for menu and tool tips"

1. Click "start" - "control panel"
2. Double click "display" in "control panel"
3. Click "appearance" tab in "display" attribute
4 In the "appearance" tab, click "effects"

5. In the "effects" dialog box, clear the check box in front of "use transition effects for menus and tool tips", and then click "OK" twice

method 2: when using the right mouse button to click on a file or directory, first use the left mouse button to select your target file or directory. Then use the right mouse button to pop up the shortcut menu<

the solution of 100% CPU usage

generally speaking, if the CPU usage is 100%, our computer will slow down. In many cases, we can solve the problem by making a little change, without having to ask the prawns

when the machine slows down, the first thing we think of is the task manager. Let's see which program accounts for the larger proportion. If it's a large program, it's forgivable. After closing the program, as long as the CPU is normal, it's OK; If not, you need to see what kind of program it is. When you can't find out what the process is, go to Google or search. Sometimes it's useless to just finish. Under XP, we can turn off some unnecessary items by combining with the startup items in msconfig. In 2000, you can use it in the next WinPatrol

some commonly used software, such as the browser takes up a lot of CPU, so we need to upgrade the software or simply replace it with other similar software. Sometimes the software and the system are a little incompatible. Of course, we can try the compatibility item given to us under XP system, right-click the. EXE file and select compatibility

sometimes svchost.exe is a headache. When you see that one of your svchost.exe takes up a lot of CPU, you can go to the next APIs or fport to check its corresponding program path, that is, what is using this svchost.exe, if it is not C: \ Windows\ System32 (XP) or C: &? 92; winnt\ System 32 (2000), that's suspicious. Upgrade anti-virus software

right clicking on a file causes 100% CPU usage, which we also encounter. Sometimes right clicking pause may be the problem. The official explanation: first click the left key to select, and then right-click (not very understanding). Unofficial: right click on the desktop - properties - appearance - effects, cancel, and use the following excessive effects (U) for menus and tool tips. Some anti-virus software will also affect the file monitoring. You can turn off the file monitoring of anti-virus software; The same is true for monitoring web pages, plug-ins and e-mails

sometimes this phenomenon may occur in some drivers. It's better to choose Microsoft certified or officially released drivers to install them. Sometimes you can upgrade the drivers appropriately, but remember that the latest is not the best

CPU cooling software, because the software will use all the CPU idle time to cool down when it is running, but windows can't distinguish the difference between the ordinary CPU occupation and the cooling instruction of the cooling software, so the CPU always displays 100%, so there's no need to worry about it, and it doesn't affect the normal operation of the system

when dealing with large word files, because word spelling and grammar checking will make CPU tired, just open the word tool options spelling and grammar and remove the check spelling and grammar check

after clicking avi video file, the CPU utilization is high because the system needs to scan the file first, check all parts of the file, and build an index; Solution: right click the folder where the video files are saved - properties - General - advanced to remove the check that allows the indexing service to index the folder for quick search<

case analysis of 100% CPU utilization

1. Dllhost process causes 100% CPU utilization

features: the normal CPU consumption of the server should be less than 75%, and the CPU consumption should fluctuate up and down. The CPU of the server with this problem will suddenly stay at 100% level, and will not decline. Looking at the task manager, you can find that dllhost.exe consumes all the CPU idle time. In this case, the administrator has to restart the IIS service. Strangely enough, everything is normal after restarting the IIS service, but the problem may appear again after a period of time

direct cause:

one or more access databases are damaged in the process of reading and writing for many times. When Microsoft's MDAC system writes the damaged access file, the ASP thread is in the block state. As a result, other threads can only wait, IIS is deadlocked, and all CPU time is consumed in dllhost<

solution:

install the "first-class information monitoring and interception system", use the "chief file inspector IIS health inspector" software,

enable "search deadlock mole", set:

-- wblock = yes
monitoring directory, please specify your host's file directory:
-- wblockdir = D: &# 92; Test

the file of the log generated by monitoring is saved in the log directory of the installation directory, and the file name is logblock.htm

stop IIS, start "chief file inspector IIS health inspector", and then start IIS, "chief file inspector IIS health inspector" will record the last access file written in logblock.htm

after a period of time, when the problem comes out, for example, the CPU will be at 100% level again. You can stop IIS and check the last ten files recorded by logblock.htm. Note that the most problematic file is the access file of the counter class, such as * * count. MDB and * * count. ASP, You can first delete the last ten files or suspected files to the recycle bin, and then start IIS to see if the problem occurs again. We believe that after careful search, you can definitely find this file that you have been worrying about for a period of time

after you find this file, you can delete it, or download it, and fix it with Access2000

2. Svchost.exe causes 100% CPU utilization rate

in the win.ini file, under [windows], the "run =" and "load =" are possible ways to load "Trojan horse" programs, so we must pay close attention to them. In general, there is nothing after their equal sign. If you find that the path and file name are not familiar startup files, your computer may be Trojan horse. Of course, you have to see clearly, because many "Trojans", such as "AOL Trojan Trojan", disguise itself as command.exe file. If you don't pay attention, you may not find that it is not the real system boot file

in the system.ini file, there is a "shell = file name" under [boot]. The correct file name should be "explorer. Exe", if not

4. This is the reason why the CPU is too bad
change

6. If it's a single machine, use the code. If it's a server, see if anyone is willing to use the giant eagle to save you. If not, commit suicide.

7. Some people play, but not many people play, because Jiaotu and laotu all have a variety of special dragons. Jiaotu also has dragons to train, and laotu has almost all dinosaurs
moreover, Jiaotu and laotu mainly have open terrain and mainly land, while the island map is mostly water area and archipelago, which greatly reces the practicability of land dinosaurs. It's also difficult to settle down. It's hard to find an open land. There are a lot of islands, hillsides and stone forests, and it's hard to take them away from floating island or volcanic island after you train the dragon, and there are too many rivers and sea areas, It is bound to rece the number of land dinosaurs and air units (for example, Fengshen usually refreshes in the mountains or woods, but can't brush on the water), which makes many players feel that there are some pits.

8. Computers can access Qunhui's shared folder through CIFS. But Qunhui seems unable to load the computer folder.

9. It's easy for gamers to change their cloud into group control. Just apply directly with their account and password. For details, you can ask Xiaorong's official website or add xrzhuzhou. The key is whether you have a good group control project
