如何清除MacOSX上的目录/ inode缓存 [英] How to clear directory/inode cache on MacOSX

问题描述

如何在Mac OSX上清除文件系统缓存（例如目录缓存和inode缓存）？我想在寒冷的MacOSX机器上做一些性能分析。我想知道是否有任何方法像 echo 3> / proc / sys / vm / drop_caches 在Linux机器上？

解决方案

purge（8）对你有用吗？

清除可以用来近似初始启动条件用于性能分析的冷
磁盘
缓冲区高速缓存。它不影响通过malloc，vm_allocate等分配的匿名内存。

How to clear file system cache (e.g. directory cache and inode cache) on a Mac OSX? I would like to do some performance analysis on a cold MacOSX machine. I am wondering that is there any approach like echo 3 > /proc/sys/vm/drop_caches on a Linux box?

解决方案

is purge(8) any use to you?

Purge can be used to approximate initial boot conditions with a cold disk buffer cache for performance analysis. It does not affect anonymous memory that has been allocated through malloc, vm_allocate, etc.
