A large number of worms are rapidly replicating inside the system, resulting in a high CPU resource occupancy rate. Solution: Clean the system memory and local hard disk thoroughly with reliable anti-virus software, and open the system setup software to see if there are any abnormal startup programs. Update and upgrade anti-virus software and firewall regularly, strengthen anti-virus awareness and master correct anti-virus knowledge. | cy1mi @/

When a computer with Windows XP installed as a server receives a connection request on port 445, it will allocate memory and a small amount of CPU resources to serve these connections. When the load is too heavy, the CPU utilization rate may be too high, because there is an inherent trade-off between the number of work items and the response ability. You need to determine the appropriate MaxWorkItems settings to improve the system responsiveness. If the set value is incorrect, the responsiveness of the server may be affected, or a user monopolizes too many system resources. L! Uq} 2y * r

When the machine slows down, of course, the first thing we think of is the task manager, to see which program accounts for a large proportion. If it is a big program, it can be forgiven. After closing the program, as long as the CPU is normal, it will be fine. If not, then you need to see what program it is. When you can't find out what this process is, go to google or baidu to search. Sometimes it is useless to just finish. Under xp, we can combine the startup items in msconfig and turn off some unused items. In 2, you can go to the next winpatrol to use it. Nt UH:>

some commonly used software, such as the browser, takes up a lot of CPU, so it is necessary to upgrade the software or simply replace it with other similar software.

svchost.exe is sometimes a headache. When you see that one of your svchost.exe takes up a lot of CPU, you can go to the next aports or fport to check its corresponding program path, that is, what is using this svchost.exe, if it is not under c:Windowssystem32(xp) or C: Winner System 32 (2), it is suspicious.

Right-clicking a file causes 1% CPU usage, which we will also encounter. Sometimes right-clicking to pause may be the problem. Official explanation: first click the left button to select, and then right click (not very understandable). Unofficial: By right-clicking on the desktop-Properties-Appearance-Effects, cancel "Use the following excessive effects for menus and tooltips". There are also some anti-virus software that will affect the file monitoring, and you can turn off the file monitoring of anti-virus software; There is also the same reason for monitoring web pages, plug-ins and emails.

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 ordinary CPU occupation and cooling instructions of cooling software, so the CPU always displays 1%, so there is no need to worry about this and it will not affect the normal system operation. knzSX

features: the normal CPU consumption of the server should be below 75%, and the CPU consumption should fluctuate up and down. In a server with this problem, the CPU will suddenly stay at the level of 1% and will not decline. Looking at the task manager, we can find that DLLHOST.EXE consumed all the CPU idle time. In this case, the administrator had to restart the IIS service. Strangely, everything was normal after restarting the IIS service, but after a while, the problem appeared again. CFTZchyk
