第一步:找到最耗CPU的进程pid // 执行 top 命令,按shift + p 组合键,按照CPU占用率排序 > top 1. 2. 从图中,我们可以看到进程pid为 11168 的占用CPU是最高的,直接是100%。 第二步:找到最耗CPU的线程tid // 执行 top -Hp [pid] 定位应用进程对应的线程 tid // 按shift + p 组合键,按照CPU占用...
(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), 还采取了两种主要Cache方式:Buffer Cache和Page Cache。前者针对磁盘块的...
top command-linux下用top命令查看cpu利用率超过100% 1. 这里显示的所有的cpu加起来的使用率,说明你的CPU是多核,你运行top后按大键盘1看看,可以显示每个cpu的使用率,top里显示的是把所有使用率加起来; 2.查看CPU信息; cat /proc/cpuinfo 3.official explanation: man top re: https://blog.csdn.net/huangsha...
The command-line utility “lscpu” in Linux is used to get CPU information of the system. The “lscpu” command fetches the CPU architecture information from the “sysfs” and /proc/cpuinfo files and displays it in a terminal. Login to SA command line with root credentials. Enter command:ls...

This works by WSL detecting that you’re idle by seeing if CPU usage is continuously low for 5 minutes, and then we start reclaiming cached memory by usingthe cgroup memory.reclaim feature. We reclaim a fixed portion of your VM’s memory size, which is calculated so that if your VM was...
