Cause of 100% CPU resource usage in Win7 and solution 1. the driver has not been certified, resulting in 100% CPU resource usage. A large number of Beta drivers are flooding the Internet, leading to hard-to-find fault causes. 2. faults caused by anti-DDoS and anti-virus software. Some anti-virus software has added rand

Thanks to grapeot for its inspiration, powershell is used to draw a pie chart showing the CPU usage of processes. I also made a Linux version. I am not familiar with gnuplot and do not know if I can draw a pie chart. Here I use a simple and easy-to-use Google API. First, let's take a look at the static pie chart of the Google chart API: Let's take a look at the pie chart in the visualization API just re

Symptom: The sslspider(sslcertificate scanning service provided by iocpis is used to run a session (concurrency). A svchost.exe of the system is always full of a CPU kernel (4 cores in total ). Analysis: This process runs four services: it is useless to stop winrm and Dnscache, and it is time-out to stop NlaSvc. It should be a strange thing, Google... It is really it! 「 What Others encounter does not seem to find a solution Http://www.tomshardware.

On-line Java application, in the peak of the Business Times often appear CPU run high, need to see real-time thread CPU situation, the following is a very good script, you can quickly export the CPU of each thread, combined with Jstack log, to the specific thread class name. First, get the process ID of the JVM:

In IIS6, w3wp memory usage often fails to be released in time, resulting in slow server response. I have studied the following configurations today: 1. apply each website separately in IIS.ProgramPool configuration. That is, they do not affect each other. 2. Set the recycle time of the application pool. The default value is 1720 hours, which can be modified as needed. At the same time, set the number of w3wp processes that run simultaneously to 1. Whe

memory that can be appropriated.The third line of data is swap partition swap, which is what we typically call virtual memory . (swap is frequently used to indicate that there is not enough physical memory.) WORKAROUND: 1.top See which processes consume more memory and kill them; 2.reboot server can effectively release swap)In order to improve disk access efficiency, Linux has done some careful design, in addition to the Dentry cache (for VFS, speed up the file path name to Inode conversion), b

Solution:1. The driver has not been certified, resulting in 100% of CPU resources. A large number of beta drivers are flooding the Internet, leading to hard-to-find fault causes.2. Faults caused by anti-DDoS and anti-virus software. Some anti-virus software has added random monitoring of web pages, plug-ins, and emails, which undoubtedly increases the burden on the system. You can choose to enable the service as needed.3. Viruses and Trojans. A large

not be reduced. A server with a large memory can be set to 0 or a large number. Servers with small memory can be set to 30, 50, or 100 to prevent memory overflow.Another solutionIf you have no problem before, and suddenly there is a problem and the server has installed Kingsoft drug overlord, this may be because Kingsoft drug overlord or the upgrade Genie has modified WINSOCK.SolutionRun the following command in Windows cmd: The code is as follows:Copy code Netsh winsock reset There may al

When migrating a database to a multi-database server, in order to save time, we may directly detach a database and then directly use the MDF file to attach the database to another server. In this case, all cache plans will be cleared out of the buffer zone. As a result, the CPU usage will remain high for a period of time. Apart from separation, the cache will be
