Transferred from: http://www.kuqin.com/shuoit/20140219/338066.htmlFor system and network administrators, it is a heavy task to monitor and debug the performance of Linux systems on a daily basis. After 5 years working as an administrator in the IT field as a Linux system, I gradually realized how difficult it was to monitor and keep the system up and running. For

and customization of the system may be different, the performance of the system cannot be generalized. Therefore, you can determine whether the system has performance problems by checking the performance expectations of a system. Therefore, we need to first set a baseline data, that is, to calculate the data of each indicator in an acceptable state. You can use

Welcome to this column. This new Linux column demonstrates and compares the performance of the Linux and Windows 2000 operating systems. Columnist ed Bradford compares the operating system-level features, rather than applications, so that people can understand the best performance characteristics of each operating syst

1. top-Linux System process monitoringThe top command is a performance monitor that can be used in many Linux/unix versions, and it is also a tool for monitoring system performance often used by Linux system administrators. The TOP command periodically displays all running a

(ext3, JFS, XFS, and ReiserFS) and what types of Hard Disks (IDE and SCSI) are used by the Linux File System, the file system tends to be fragmented over time. Ext3, JFS, and other advanced file systems can reduce file system fragmentation, but they are not eliminated. In a busy database server, file fragmentation will reduce the hard disk performance over time, and the hard disk

differences for an enterprise customer is whether the virtual memory address can exceed 4GB.From a performance perspective, it is important to understand how the Linux kernel in 32-bit and 64-bit systems maps physical memory to virtual cores.From Figure 1-10, you can see the obvious difference in how the Linux kernel handles 32-bit and 64-bit system memory.The m

Advanced file systems such as EXT3 and JFS can reduce the fragmentation of file systems, but not eliminate them. In a busy database server, over time, file fragmentation

Operating systems are getting more and more attention from computer users. The Linux operating system is also the most famous example in the development of free software and open source code. Before introducing various tuning parameters and performance monitoring tools for Linux systems, we need to discuss some performance
