What is RSS memory in Linux?

In computing, resident set size (RSS) is the portion of memory 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.

If you have a memory leak it’s routine for your RSS to stay constant while your VSZ grows. After all, you aren’t looking at that leaked memory any more. A large RSS on an active system (one under memory pressure) means that your process touches a lot of memory (often rapidly) during its operation.
