第三行数据是交换分区SWAP的,也就是我们通常所说的虚拟内存。(Swap被频繁使用时,说明物理内存不足。解决方法: 1.top查看哪些进程消耗较多内存,kill掉它们;2.reboot server能有效地释放swap) 为了提高磁盘存取效率, Linux做了一些精心的设计, 除了对dentry进行缓存(用于VFS,加速文件路径名到inode的转换), 还采取了...
The ps command can be mixed with various options to show the list of top processes sorted by RAM and CPU usage. Run the following command in Terminal to see the top running processes by RAM and CPU usage: $ ps -eo pid,ppid,cmd,%mem,%cpu --sort=-%mem | head Below is the screens...
There are two popularways to check disk usage in Linux terminal: du command and df command. Thedu command is more for checking the space used by a directoryand the df command gives you the disk utilization on filesystem level. The gdu tool sorts of combined the functionality of both. ...
You can easily check CPU load, the number of current tasks, as well asviewing information about memory usage. You’ll notice that while running there are essentially 2 sections with information. At the top of our terminal, we get our overview data including memory usage and cpu load. Below...
