From the topic above, you may have remembered one of our former post “what data is cached by operation system“. This is a similar tool as Fincore, but it’s more powerful. It’s written in C and supports UNIX and unix-like systems.
The installation is quite simple, you just need to download the source code, and run below command to compile it:
$ gcc -Wall -O3 -o vmtouch vmtouch.c
The usage examples can be seen at its homepage.
Its key features are:
- How much data of a file (or a directory) is currently in cache.
- Bring a file (or part of a file) into system memory.
- Ask the system to evict a specified file from memory, making room for other files.
- Daemonise and lock specified files into physical memory (Make sense?)

Enjoy!
