In Linux, we know thatNice, reniceCommands change the execution priority of processes, and high-priority processes give priority to execution, so as to ensure the running of important tasks to a certain extent. In addition to Nice and renice, you can use CPU affinity to specify the processors on which processes are running. CPU affinity indicates the tendency of a process to run on a given

From http://blog.csdn.net/Treeyan In fact, it is not original. The materials are mostly from the Internet through Google. Some time ago I bought a hp-dv1702 laptop, core Single Core CPU, 5400 turn hard disk, watch a movie very good. the core CPU supports the speedstep technology. When you are not busy, it always works at around 800 MHz, with a low calorific value. The BIOS sets the fan start temperature to

To adjust the use of a CPU for a program: First, use Taskset to make full use of multi-core CPU, so that the utilization of the CPU is balanced to each CPU #taskset-P, set an existing PID instead of reopening a new task-C, specify a processing, you can specify multiple, comma-delimited, or specify a range, such as: 2

CPU, generally think that write-C + + needs to understand, write high-level language (Java/c#/pathon ...) There is no need to understand the underlying stuff. I thought so at first, but until I met Lmax's disruptor, as well as Martin's blog post, I found that Java was more than a CPU to ignore. After a period of reading, hope to summarize their reading after the sentiment. This paper mainly talks about the

This article primarily records the Tomcat process, which causes the CPU to take up too high a number of problems with TCP connections. Problem Description Under Linux, a Tomcat Web service has a very high CPU footprint and the top display results over 200%. The request cannot be answered. Repeated restart is still the same phenomenon. Problem Troubleshooting 1. Get process information The JPS command provid

Starting with Java 5, the JDK provides some JVM detection APIs, a well-known java.lang.management package that provides many Mxbean interface classes that are easily accessible to the JVM's memory, GC, Thread, lock, class, Even the operating system level of various information, this article simply introduces a Java process using JMX CPU, heap memory use of monitoring. Some people may feel that there is no need to do this, because tools such as jconsol

Recently, the company server has always been cpu100% occupied, the server is configured as dual-core xeon3.0x2,2g ECC memory. The discovery is that w3wp.exe takes up a large amount of CPU for a long time. This situation should be caused by the death cycle of the website program. You can temporarily limit the w3wp process CPU usage before you find a problem to ensure that the site can work: Under IIS6, frequ

Original link: http://blog.uwa4d.com/archives/optimzation_cpu.html Performance optimization is an eternal topic in the development of game projects. Player needs and project requirements are constantly growing, with the number of people, screen effects and the complexity of the scene is always approaching the trend of "squeeze dry" hardware. Therefore, regardless of the level of hardware equipment development, no matter how rich experience in the development team, performance optimization is alw

Article Title: Linux performance monitoring and tuning (CPU ). Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In fact, there are many articles on this part on the Internet. Why is this article still available? There are several reasons why it is the motivation of my translation. First, although concepts and conten

Bus structure of the CPU each device to do what things, generally through the control signal control, control signal all determine the state of the bus structure. All control signals are from the controller. The control signal is generally set up separately for the transmission of the line, each signal has its own direction and target. Therefore, the internal control line of the CPU is more dedicated, rathe

CPU address space(1) concept of address 1) physical address: the address sent from the CPU address bus, which is controlled by the hardware circuit. A large part of the physical address is reserved for memory in the memory, but it is often mapped to other memory. (Such as video memory and BIOS ). After the virtual address in the program instruction passes the field ing and page ing, a physical address is ge

Author: Yao Zhen, Shanghai Why is the actual frequency of only 2500g amd + processor running faster than the actual frequency of 2G P4-2.4B is faster? Why is the tulatin core processor with a 0.13 micron process capable of achieving a maximum of 1.4 GB? Instead, the Willamette core processor with a 0.18 micron process can easily achieve 2 GB? Next, let's analyze why the above two "strange circles" exist. Each CPU has an "execution Pipeline" (hereinaft

Android obtains information about the cpu, memory, version, and power of the system. 1. CPU frequency and CPU information:/proc/cpuinfo and/proc/stat.By reading the file/proc/cpuinfo system CPU type and other information.Read/proc/stat all CPU activity information to calcula

When using a system, we must look at the system configuration, while the CentOS system looks at the configuration, it is not as intuitive as windows. You can only view them one by one. Many people are overwhelmed by how to view the CPU Of The CentOS system. Next, let's learn how to view the CPU in the CentOS system. I. CentOS system cpu [Root @ srv/] # more/proc/

First-come first-served scheduling and FCFS schedulingAlgorithm(Non-preemptible) When a process enters the ready queue, its PCB is linked to the tail of the queue. When the CPU is idle, the CPU is allocated to the process in the queue header. Then, the running process is deleted from the queue. FCFS schedulingCodeEasy to write and understand. Shortest job priority scheduling algorithm, SJF scheduling

Basic Concept 1 records in a queue are usually process control blocks of processes. 2 CPU scheduling decision can occur in the following four environments: A. When a process switches from running to waiting, for example, i/O requests or calls wait to wait for the termination of a sub-process. For example, when a process switches from the waiting state to the interrupted c state, for example, I/O completed D. When a process is terminated, the schedulin

Two-way authentication for user cards and machines Question: 1. Traditional "dark signs" Classic clips:Q: Tianwang gaidihuA: Baota Zhenghe demon Shake hands and hug each other, comrade! Finally, I found you. I believe that everyone will have seen the dark part in the spy movies, but the dark part is easy to be stolen by the enemy, so there is a thrilling or tragic story of the revolutionaries, of course, there are some traitors selling. Security Analysis:We are very impressed with the fact that

During system maintenance, it may be necessary to review the CPU usage at any time, and to analyze the system condition according to the corresponding information. In CentOS, you can view CPU usage by using the top command. After running the top command, the CPU usage status is displayed in full-screen mode, and will be in the dialog-using top-based commands, you
