RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. It does not include memory that is swapped out. It does include memory from shared libraries as long as the pages from those libraries are actually in memory. It does include all stack and heap memory.RSS is the Resident Set Size
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.
What is RSS in top command?
RSS stands for Resident Set Size and shows how much RAM is utilized at the time the command is output. It also should be noted that it shows the entire stack of physically allocated memory. VSZ - Virtual Memory Size.
The resident set size (RSS) is the amount of space of physical memory (RAM) held by a process. The value is typically specified in bytes or pages. If the full amount of space required by a process exceeds the RSS, the remaining portion is typically stored in swap. Collectively, the total amount is the virtual set size.
RSS (RDF Site Summary or Really Simple Syndication) is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format.
We do have RSS Feed Size limits that we employ to make posting more efficient for our Users. For our Basic plan users, this limit is 512 KB, and for our Pro users, this limit is 1536 KB. Though it is rare, some Feeds do end up exceeding this limit.
4. Using RSS and VSZ4.1. Using ps. One of the ways to check the RSS and VSZ for Linux processes is to call ps: $ ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.1 0.0 169316 13184 ? 4.2. Using top. Another useful command to check on processes is top.13 Aug 2020

Really Simple Syndication No, RSS actually stands for Really Simple Syndication – an XML-based format for sharing and distributing Web content. In laymans terms, RSS allows you to subscribe to a news feed from your favorite Web site (you know its the Library of Congress) and receive automatic updates from that site as they become available.
Part of the RSS is allocated in real memory blocks (other than mapped into a file or device). This is anonymous memory (anon-rss) and there is also RSS memory blocks that are mapped into devices and files (file-rss).
What is VSS and RSS in top command?
Vss = virtual set size. Rss = resident set size. Pss = proportional set size. Uss = unique set size.

What does anon RSS and total VM mean?
121. As I understand, the size of the virtual memory that a process uses is listed as total-vm. Part of it is really mapped into the RAM itself (allocated and used). This is RSS. Part of the RSS is allocated in real memory blocks (other than mapped into a file or device).
What is VM Min_free_kbytes?
min_free_kbytes: This is used to force the Linux VM to keep a minimum number of kilobytes free. The VM uses this number to compute a watermark[WMARK_MIN] value for each lowmem zone in the system. Each lowmem zone gets a number of reserved free pages based proportionally on its size.
What is VSZ and RSS?
RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.
