Talking about linux performance tuning 9: changing system default limits; talking about linux performance tuning 8: Removing unnecessary overhead http://www.2cto.com/os/201307/228393.html After reading the first two articles, we are trying to save resources for our real services. Problem: our service is actually used..

Linux performance monitoring and analysis tool background recently, a pre-developed system performance test is required. The system is deployed on the Linux server cluster. In high concurrency and high load scenarios, you can collect all the information (including CPU, memory, I/O, disk, and network traffic) occupied b

Nmon (also known as Nigel rsquo; sMonitor) is a very common system performance monitoring tool developed by IBM engineer nielgriiths and suitable for AIX and Linux operating systems. This tool can directly display the resource utilization of the current operating system on the screen to help you identify system bottlenecks and assist in system tuning. Thanks to its fame, we have made a simple recommendatio

How to Use Nmon to monitor Linux system performance Nmon (also known as Nigel's Monitor) is a very common system performance monitoring tool, developed by IBM engineer Nigel Griffin iths, applicable to AIX and Linux operating systems. This tool can directly display the resource utilization of the current operating syst

Nmon (named Nigel's Monitor) is a computer performance system monitoring tool developed by IBM employees Nigel Griffiths for AIX and Linux systems. Nmon can display the operating system statistics on the screen or stored in a data file to help understand the use of computer resources, adjust direction and system bottlenecks. This system benchmark tool only needs to use one command to get a lot of important

Nmon is a tool for collecting performance data and analysis of Aix or Linux hosts and is easy to use. There are two main, one is the Nmon collection Data tool, the general name is nmon_**, for example nmon_aix5.3, another is the analysis result tool, it is an Excel file, the name is: Nmon analyser v33a.xls.Nmon displays all important performance tuning informatio

Article Title: Improve socket performance on Linux. 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. When developing a socket application, the first task is to ensure reliability and

Use Dstat for Linux Comprehensive Performance Diagnosis Performance testing, evaluation, and optimization have always been the focus of system management and maintenance personnel. When we analyze a production application, obtaining basic data such as CPU, memory, IO, network throughput, and process load is crucial for subsequent

3.3 memory bottleneckOn a Linux system, using programs run at the same time.These programs support multiple users, and some processes are more used than others.Some of these programs use a portion of memory while the rest are "sleeping ."When an application accesses cache, the performance increases because an in-memory access retrieves data,Thereby eliminating the need to access slower disks.In a

In previous posts on vm.swappiness and using RAM disks we talked about how the memory on a Linux guest are used for the OS itself (the kernel, buffers, etc), applications, and also for file cache. File caching is an important performance improvement, and read caching are a clear win in most cases, balanced against APPL Ications using the RAM directly. Write caching is trickier. The

 CPU performance Explore-linux cache mechanismBefore reading the article, you should have basic knowledge of the memory hierarchy, at least to understand the principle of locality. To learn more about the cache fundamentals, you can refer to this book, "in-depth understanding of computer systems" in the Memory Architecture chapter:With questions to read the article, the cache is not visible to programmers

The first two experiences the QEMU and KVM accelerated qemu, and experience the third-party virtual machine management tool Virt-manager, giving us a glimpse of the high quality and high performance of the open source community's powerful and open-source virtual machine software. In this article, let me dissect the VirtualBox. VirtualBox claims to be the most powerful virtual machine product in the current open source industry, and on the
