Resident set size
{{Short description|A computer process and data in RAM}}

In computing, resident set size (RSS) is the portion of memory (measured in kilobytes) occupied by a process that is held in main memory (RAM). The rest of the occupied memory exists in the swap space or file system, either because some parts of the occupied memory were paged out, or because some parts of the executable were never loaded.{{cite web
