In actual development, it is found that sometimes the usage of self-developed programs is very high, which affects the normal operation of other programs on the machine. What should we do at this time?
The first thing to think of is that the best solution is to find the thread with the most CPU usage in the
The first is to get a particular process object, either by using the Process.getprocesses () method to get all the processes running on the system, or by using the Process.getcurrentprocess () method to get the process object that the current program corresponds to. When you have a process object, you can create the PerformanceCounter type object by using the

527814231, fault phenomenonCustomer Service colleague Feedback platform system runs slowly, the webpage is serious, the problem persists after restarting the system several times, using the top command to view the server situation, found that the CPU occupancy rate is too high.2, high CPU consumption problem location 2
The reason for high CPU usage
1. The computer runs a large program, such as large games, 3D network games and so on, this situation is usually normal, such programs require more CPU resources, users will be large program exit for a period of time, the CPU utilization rat
This article uses Java processes to illustrate 1. View the CPU usage of the Java process and its threads First use PS-EF to find the Java process ID # ps-ef|grep Java Then use the top-p PID command to view the CPU used by the process

Friend Host (Windows 2003 + IIS + PHP + MySQL) recently the MYSQL service process (Mysqld-nt.exe) CPU occupancy rate of total 100% high. This host has 10 or so database, respectively, to 10 web site calls. According to a friend test, resulting in Mysqld-nt.exe CPU consumption is a very

Obtain the CPU usage of a process
// Time conversion static _ int64 file_time_2_utc (const filetime * ftime) {large_integer Li; Li. lowpart = ftime-> dwlowdatetime; Li. highpart = ftime-> dwhighdatetime; return Li. quadpart;} // obtain the number of CPU cores. Static int get_processor_number () {system_info Info; gets
In performance tests, top commands are often used to monitor the CPU and memory usage of a process over a period of time. Output to the file once every 10 seconds. The following code processes the output top file and obtains the CPU utilization. memory has the largest, minimum, and average value. Topfile = raw_input ("
There are many friends who use the mysql database server, and we often encounter mysql process CPU usage of 100%. Below I will summarize some solutions.
There are many friends who use the mysql database server, and we often encounter mysql process CPU
Many times, when we test the program in the background, we need to monitor the program's memory and CPU usage for a period of time, but can not always stare at the output of the top command.This time we need to use a script to help us record this information, convenient for us to monitor.Nonsense not much to say, directly on the code:```shell#!/bin/bashFileName="res.txt"echo "%
This article describes how to obtain the memory and CPU usage information of a single process.
Memory consumption: VSS/RSS/PSS/USS
Terms• VSS-virtual set size virtual memory consumption (including memory occupied by shared libraries)• RSS-resident set size actually uses physical memory (including memory occupied by shared libraries)• Pss-proportional set size phy
This article describes the way to get CPU usage of the system process under Linux through the Go language. Share to everyone for your reference. The specific analysis is as follows:
This code uses Linux's System command PS to analyze CPU usage, as follows:
Copy Code c
PS-Aux | sort-K4, 4n
PS auxw -- Sort = RSS
PS auxw -- Sort = % CPU
CPU usage of the ps command % CPU process in Linux% Mem process memory usageThe size of the virtual memory used by the vsz ProcessThe size of the resident set or a
