Solve the problem of high CPU usage in WinXP

[article REVIEW]

when the connection request is overloaded, it may cause excessive CPU usage, resulting in a sharp decline in system performance, or even enter a state of suspended animation ......
have such a Phenomenon, when a computer with Windows XP receives a connection request on port 445, Windows XP allocates memory and allocates a small amount of CPU resources to service these connections. When the connection request load is too heavy, the CPU usage may be too high, resulting in a sharp drop in system performance or even a suspended animation.

Reason for the problem:

This is due to the "proportional misalignment" between the number of windows XP work items and the responsiveness. If there is a suitable MaxWorkitems setting, the system responsiveness can be improved.

Solution:

Click "Start" → "Run", enter "Regedit" in the run dialog box, click "OK", open the registry editor, and then expand the following sub-keys :HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\lanmanserver, create a new DWORD value named "Maxworkitems" in the right window, and then double-click it, in the "Edit DWORD Value" dialog box that pops up, according to the memory capacity of the computer. Determine the key value of the key. If the computer memory is less than 512MB, type "256"; if the memory is larger than 512MB, set it to "1024". When you are done, exit the Registry Editor and restart your computer to take effect.
