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...
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...
将列出cpu的详细信息。 在系统维护的过程中,随时可能有需要查看 CPU 使用率,并根据相应信息分析系统状况的需要。在 CentOS 中,可以通过 top 命令来查看 CPU 使用状况。运行 top 命令后,CPU 使用状态会以全屏的方式显示,并且会处在对话的模式 -- 用基于 top 的命令,可以控制显示方式等等。退出 top 的命令为 q ...
(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...
