三大Linux command查看CPU和Memory的使用情况 1. top command :是linux下常用的性能分析工具,能够实时显示系统中各个进程的资源占用状况。 2. free command : free -m查看内存占用情况 free -S不间断地监控有多少内存在使用 --- For example : total used free shared buffers cached Mem: 128 119 8 0 1 22...
1. free command The free command is the most simple and easy to use command to check memory usage on linux. Here is a quick example $ free -m total used free shared buffers cached Mem: 7976 6459 1517 0 865 2248 -/+ buffers/cache: 3344 4631 ...
Check Linux memory usage with the free command To check available free memory and swaps, use thefreecommand. Just run the command like bellow, no root privilege required. free -h It's worth to pass few more command line arguments to get more convenient results. ...

非一致性内存访问 NUMA(Non-Uniform Memory Access)意思是内存被划分为各个node,访问一个node花费的时间取决于CPU离这个node的距离。每一个cpu内部有一个本地的node,访问本地node时间比访问其他node的速度快一致性内存访问 UMA(Uniform Memory Access)也可以称为SMP(Symmetric Multi-Process)对称多处理器。意思是所有...
