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...

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...
