Thanks for the answer but this doesn't answer my question. Obviously I have shared RAM. My question was, does linux store frequently used files in RAM ? Because this is usually reported in the free -m command output.

But in the case of OpenVZ VPS I see nothing (0) in the cached and buffers column.

I researched a little, the system caches files, they are just not reported.
