Many people in the process of using a notebook, often pay attention to their CPU performance, we will see the notebook CPU model behind the usual "U", "M" and other words, and "u" is the meaning of low pressure, "M" is the meaning of the standard pressure. Recently, a lot of net users of notebook CPU low-voltage and high-pressure difference is not very understand

Objective:Performance optimization is a commonplace topic, typical performance problems such as slow page response, interface timeout, high server load, low number of concurrency, database frequent deadlock and so on. Especially in the "rough fast" Internet development model of the big line today, with the increasing number of system access and code bloated, a variety of performance problems began to pour.There are three factors that can affect application performance at the system level:

In the absence of nagios monitoring software, as long as the server can be on the Internet, you can send mail to remind the Administrator system load and CPU usage. First, install the following Linux mail client msmtp software (similar to a foxmail tool) 1. Download and install:Http://downloads.sourceforge.net/msmtp/msmtp-1.4.16.tar.bz2?modtime=1217206451big_mirror=0 Copy Code code as follows: # tar JXVF msmtp-1.4.16.tar.bz2 # C

Linux CPU metrics Linux provides a wealth of commands to monitor CPU-related data, such as top and vmstat. Top is a dynamic display process, that is, you can press the key to continuously refresh the current status. If you execute this command on the foreground, it will exclusively occupy the foreground until the user terminates the program. More accurately, the top command provides real-time monitoring of

When we use the Windows XP operating system, the system slows down when we use it. When we look at "Task Manager", we find that the CPU usage reaches 100%. How did this happen? In this article, I will explain why the system resource usage reaches 100% from three aspects: hardware, software, and virus. CPU usage is usually 100%, and the main problems may occur in the following aspects: Nine possibilities of

Intro-----Usually when we write server code, we can improve the efficiency of the system scheduler by binding the current process to a fixed CPU core or thread binding to a fixed CPU core, and then paste the complete code below.```/************************************************* This routine explains the process, thread binding to a fixed CPU core running on* T

CPU as the core part of the computer, the frequency of failure is relatively low, in many cases, the failure of the processor is due to the motherboard problem. such as the following troubleshooting, really let the author cost some twists and pains. Failure performance: a compatible machine assembled for friends in 2004, using the Intel Celeron 1.7GHz processor, has been in use for two years, the most recent in a move, love Machine is unable to start

Now in the computer market you will be pleasantly surprised to find that the configuration of more than 1Ghz CPU computer has become the mainstream of the market. When the CPU is more than 1GHz, the maintenance of the hardware CPU becomes the first important event, if still not enough attention, will cause computer failure or even crash, burn.

Recently, I have read a part of the thread of CLR via C #, which greatly improves the understanding of the thread. As a result, I suddenly remembered a book I saw in guanggu bookstore in college about Microsoft's interview. After several pages, I found that the author was talking about the problem. At that time, I felt that this author was very good at B, because the level of food at that time was still relatively good. Then I forgot. (Of course I didn't buy that book, but I didn't expect to app

Linux CPU interruption [reprinted], linuxcpu reprinted Interruption is actually a signal sent by hardware or software called IRQ (interrupt request. The interrupt allows devices, such as keyboards, serial ports, and parallel ports, to indicate that they require CPU. Once the CPU receives the interrupt request, the CPU

Hyper-V 3 limits the CPU utilization of virtual machines. Windows Server 2012 is coming soon. The latest Hyper-V 3 brings us more surprises, in the next three blog posts, we will learn about the virtual machine CPU competition mechanism. Part 1: CPU resources allocated to virtual machines; Part 2: limits the CPU usage

/proc/cpuinfo File AnalysisAccording to the following content, we can easily know the current system about the CPU, CPU, the CPU is enabled Hyper-threading and other information. Logical Core: Cat/proc/cpuinfo | grep "Processor" | Wc-l//the ID of the logical processor(number of logical cores)Query systemNumber of CPUs: Cat/proc/cpuinfo | grep "Physical ID" | Sort

No free lunch in the world, this article reproduced in: http://cenalulu.github.io/linux/all-about-cpu-cache/ Let's take a look at a mind map of all the concepts in this article:Why do I need a CPU CacheAs the process has increased in recent decades, CPU frequency has been increasing, and is subject to manufacturing processes and cost constraints, the curren

In fact, as long as #include Long num = sysconf (_SC_NPROCESSORS_ONLN); You can get the current number of CPUs ... Judge the basis:1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores. English version:1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any

CPU as the core of PC computer accessories, the probability of failure is not large. The CPU processor in normal use, if not overclocking, generally will not appear any problem. Of course, due to the cooling fan shutdown, the radiator and the CPU bad contact caused by the frequent panic, restart failure is often occurred. For some older

CPU processor is a PC computer, one of the most important accessories, the operation of various data, processing and other processes are done by the CPU processor. If a computer is compared to a human body, then CPU processor can be regarded as the human brain, control the whole machine parts of the phase to coordinate operation. Due to the high integration of

CPU is one of the main factors affecting Linux performance. Vmstat command: displays brief information about the performance of various system resources.The r in the procs column indicates the number of processes that run and wait for the CPU time slice. If this value exceeds the number of CPU for a long time, it indicates that the

The key to monitoring the CPU and memory of the switch is to find the correct OID, please refer to the following blog post for how to find the OID.http://tryrus.blog.51cto.com/10914693/1788833Before looking at this blog post please make sure that you have an understanding of the basic operation of Zabbix, there is no clear place to read my previous blog post.http://tryrus.blog.51cto.com/10914693/1772271http://tryrus.blog.51cto.com/10914693/1782062Firs
