WebJan 31, 2014 · The nice thing about using PSS is that you can add up this value across all processes to determine the actual total RAM use. This characteristic is used at the end of the meminfo report to compute how much RAM is in use (which comes in part from all non-cached processes), versus how much is "free" (which includes cached processes).
