Linux系统内存中的文件系统缓存 (File System Caching in Linux System Memory) 作用:提高文件访问效率,减少磁盘I/O操作。 影响:长时间运行或大数据处理时,可能导致内存可用空间下降。 3.2 Slab分配器与内核对象 Slab分配器(Slab Allocator)是Linux内核中的一种高效内存管理机制,用于管理内核对象的内存分配和回收。它通...
memory-usage是一个简洁且易用的命令行工具,可以快速查看系统的内存使用情况。该工具基于Linux系统的内存管理机制,通过实时监控进程的内存使用情况,为用户提供一个直观的视角。 二、使用方法 安装memory-usage 在Linux系统中,你可以使用以下命令来安装memory-usage: sudo apt-get update sudo apt-get install memor...
Linux comes with different set of commands to check memory usage. The free command displays the total amount of free and used physical and swap memory in the system, as well as the buffers used by the kernel. The vmstat command reports information about processes, memory, paging, block IO,...
