-The “proportional set size” (PSS) the tool smem reports is the memory the program plus the "fair share" of each shared area to give a realistic measure.

 ===== RSS ===== ===== RSS =====
-Most standard Unix memory tools are reporting the “resident set size” (RSS) - which roughly is the memory usage of a program plus the shared libraries it needs. Because it includes the whole shared memory it shares with other programs this isn't a fair representation of memory a program really needs.

 ===== USS ===== ===== USS =====
-The "unique set size" (USS) reports the memory needed by the program binary only, without any shared library it might need. This underestimates the programs memory footprint,unless it is a static linked binary.
