Memory usage of a process having shared libraries
Hi,
I have the following two processes that's built with static libraries. Both the process have many common libraries.
-rwxr-xr-x 1 xxx xxx 152946280 Oct 15 08:38 server1
-rwxr-xr-x 1 xxx xxx 41633880 Oct 15 08:39 server2.
I built these two server processes making all the libraries shared (with kPIC option and -G in the make file). The size of the executable get reduced significantly as shown below.
-rwxr-xr-x 1 xxx xxx 580800 Oct 15 18:40 server1
-rwxr-xr-x 1 xxx xxx 246736 Oct 15 18:41 server2.
Now when I run these processes and monitor the memory usage (using top command), I would have thought that summing up memory usage of (RES column value) the latter two processes would be less than that of the former. But what I observe is exact opposite with both the processes showing higher values in shared case.Can somebody explain why? Is the memory usage that correspond to shared library also getting included as part of process memory usage.
Also I am not sure if I can use the top command to track the memory consumption.
Please advise.
Operating system - Sun solaris 5.10

NAME
face - executable for the Framed Access Command Environment Interface
SYNOPSIS
face [-i init_file] [-c command_file] [-a alias_file] [filename...]
DESCRIPTION
The Framed Access Command Environment Interface (FACE) presents your files and file folders on the screen through a system of menus and
forms if you are properly set up as a FACE user.
filename must follow the naming convention Menu.xxx for a menu, Form.xxx for a form, and Text.xxx for a text file, where xxx is any string
that conforms to the UNIX system file naming conventions. The Form and Menu Language Interpreter (FMLI) descriptor lifetime will be
ignored for all frames opened by argument to face. These frames have a lifetime of immortal by default. If filename is not specified on the
command line, the FACE Menu will be opened along with those objects specified by the
LOGINWIN environment variables. These variables are found in the user's .environ file.
OPTIONS
The following options are supported:
-a alias_file Alias file
-c command_file Command file
-i init_file Initial file
OPERANDS
The following operand is supported:
filename The full pathname of the file describing the object to be opened initially.
EXIT STATUS
The face command will return a non-zero exit value if the user is not properly set up as a FACE user.
FILES
$HOME/pref/.environ
