Article Title: use of commercial server AIX resource monitoring and modulation tools. 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. Performance Optimization and determining the performance bottleneck in the system are one of the main tasks of the system administrator.
Turn from 51Testinghttp://bbs.51testing.com/viewthread.php?tid=116526Often see a lot of people talk about LoadRunner to Linux/aix performance monitoring too little, indeed, LR for non-Windows platform monitoring is too little, but we can use IBM's Nmon for performance analysis, this is a great tool, on the official website of IBM:Http://www-941.haw.ibm.com/collab

Disks are usually the slowest subsystem of the computer and are the most prone to performance bottlenecks because the disk is farthest from the CPU and the CPU accesses the disk to involve mechanical operations such as rotating shafts, track-seeking, etc. The speed difference between accessing the hard disk and accessing the memory is calculated in order of magni
