- | 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. At simpletools.info the PSS is the crucial criterion to determine the memory footprint of a program. The unit is kilobyte (kB). | + | 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.

- | 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.
