Do you use linux based system? Linux don't return memory once used to free, it uses it for disk buffers but it will free it when
needed. So probably much part of that system was for disk buffers and are not used by FS any more.

I always thought that memory allocated in libraries are included in process which is using them. Where it should be in your
opinion? For external services/servers memory is not included in process but this is not the case in FS. Look at RES to know how
much memory it uses.
