Known your system cache status

[edenCC]

Hi, Guys,

I just created a article on how to check how much data of a file is cached by a running operation system, please read the original version here at my tiny blog:

Generally, we can do this by two perl script:

fincore

fadvise

Thanks for your time, any comments is welcome!
