Hi Konstantin,
The first time when you connect a file, some code in shared libs
will be loaded. Also the dictionary from the classes in the file
is read to memory (but this should be small).
So 1.2 Mb looks normal. However, if you see this increase every time
you connect a file, there is a problem.
Unfortunaletly, you do not indicate which version of ROOT
that you are using. Please give more details about this problem.
