Safe way to drop cached memory

igadoter · 09-05-2012, 04:58 PM

Hi,

Some applications cause the kernel to cache great amount of RAM. And it seems for me that cached memory is somehow 'unusable' for other apps. I now that MPlayer behaves badly when a lot of the memory is cached. I want a kind of a management of the cached memory like 'drop cache when it is safe'. The problem is how to resolve when it is safe.....

Hi.
I'm not sure that it is a right link, but anyway have alook at this:
Link one
Link two
Link three

Thanks for the link one. I think that my problems are solved now. The trick is to add 'sync' command before dropping cached memory. I knew that 'echo 1 > /proc/sys/vm/drop_caches' clears the memory - but doing this forcibly may cause
data lost.
