I meant that FS can use less memory now they 24-25 M, what is RES shows is exactly that value. In those 24-25 M are buffers for
files which now are not needed for FS and kernel handles that memory. It is show as used but is not used by FS. Kernel uses it and
will free it when there will be lack of memory.

Always look at RES value if you want to know FS consumption.
