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

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The externa

In fact, the people who write Java seems to have nothing to do with the CPU, at most and we mentioned in the previous how to run the CPU full, how to set the number of threads is a bit of a relationship, but the algorithm is only a reference, many scenarios need to take practical means to solve can And we'll consider how to make the CPU not so full after the

Without nagios monitoring software, as long as the server can access the Internet, you can send an email to remind the administrator of the system load and CPU usage. 1. Install a mail client msmtp software (similar to a foxmail tool) in linux) 1. Download and install: Http://downloads.sourceforge.net/msmtp/msmtp-1.4.16.tar.bz2? Modtime = 1217206451 big_mirror = 0Unzip tarjxvfmsmtp-1.4.16.tar.bz2 # cdmsmtp-1.4.16 #./configure -- prefix =/usr/local/ms

The best synchronization technology is to put the design of critical resources that do not need to be synchronized first. This is a way of thinking, because each explicit synchronization primitive has a performance overhead that cannot be ignored. The simplest and most important synchronization technology includes declaring kernel variables or data structures as per-CPU variables ). Each CPU variable is mai

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

Let the multi-core CPU usage curve listen to your command-the beauty of programming 1.1 Study Notes Problem: Write a program to determine the CPU usage of the Windows Task Manager. There are several situations: 1. The CPU usage is fixed at 50%, which is a straight line; 2. the CPU usage is a straight line. The specific

With the increasing popularity of Linux applications, a large number of network servers use the Linux operating system. To fully measure the network running status, you need to make more detailed and accurate measurements on the network status. The establishment of the SNMP protocol provides powerful support for Internet measurement. Multirouter Traffic Grapher (MRTG) is a typical network traffic statistical analysis tool based on SNMP. It consumes a small amount of system resources, so many plu

CPU usage is actually the CPU resource that your program runs on, indicating that your machine is running a program at some point in time. Higher usage means that your machine runs a lot of programs at this time, whereas lessThe top command is a common system performance analysis tool under Linux that allows you to view the resource usage of each process in real time.Top-10:02:17 up (19:18), 4 users, load a

1. First understand the/proc/STAT File Information In Linux/Unix, CPU utilization is divided into user-state, system-state, and idle state, indicating the time when the CPU is in user-state, and the time when the system kernel is executed, and the execution time of idle system processes. CPU utilization usually refers to the time when the

What is a CPU (Critical Patch Update )? A single CPU contains the repair of multiple security vulnerabilities and patches for the required non-security vulnerabilities. CPU usage is cumulative. You only need to install the latest CPU, including all previously released CPU us

In fact, the person who writes Java seems to have nothing to do with the CPU. At most, it has something to do with how we can fully run the CPU and set the number of threads as mentioned above, but that algorithm is just a reference, in many different scenarios, we need to take practical measures to solve the problem. When the CPU is fully occupied, we will also

Recently some of the novice ready to buy a new friend, are asked about the CPU health related issues. These friends must be from where to hear the CPU has a "physical" differences, but as if not clear, how to distinguish. Today to tell you about the CPU of the "physical" what is it? DIY installed to save money to buy a chip

0. Why write this blogThe top or PS of Linux can see the CPU utilization of the process, so why do you need to know this detail? There are three reasons for writing this article:* Want to be able to get process CPU utilization in a script in a "non-blocking" way * PS cannot get CPU utilization at the current time of the process; top takes at least 1 seconds to ge

You see the CPU metrics:But what does all of those 2-letter abbreviations mean?The 3 CPU statesLet's take a step back. There is 3 general states your CPU can is in: Idle, which means it had nothing to do. Running A use

In Linux, you can view CPU and memory usage during system maintenance. you may need to view CPU usage at any time and analyze the system status based on the relevant information. In CentOS, you can use the top command to view CPU usage. After running the top command, CPU usage... in Linux, you can view

For modern CPUs, the performance bottleneck is access to memory. CPU speeds are often at least two orders of magnitude higher than main memory. So the CPU has introduced L1_cache and L2_cache, and the higher-end CPUs have joined the L3_cache. Obviously, this technique raises the next question:If the memory that a CPU needs to access at the time of execution is no

In the Linux operating system, we generally look at the CPU load of the system commonly used commands can be uptime,top, as well as vmstat and so on are all possible. The information provided by each tool is different,I'm going to talk about the CPU section here. Using the uptime command, you can get the operating system in the last 1 minutes, 5 minutes and 15 minutes of the
