So the working set is a number of pages a process demands to be loaded from memory during execution. The working set consists of the most recently loaded page and the k pages that have been loaded before. When it comes to make a frame free for a new demanded page, only pages that are not in the working set may be swapped. Working set is a subset of virtual pages resident in physical memory.

- The working set of a process is the set of pages in the virtual address space of the process that are currently resident in physical memory.
- Implementing Working Set replacement. Regularly scanning all of memory to identify the least recently used page is a very expensive process.
- One example is a modified version of the clock algorithm called WSClock. Variants. Working set can be divided into code working set and data working set.
- The term "Working Set" is related to the Working Set Page Replacement Algorithm (the algorithm is very well explained in this article of Andrew Tanenbaum).
- The working set of information is the smallest collection of information that must be present in the main memory to assure the efficient execution of his program.
- In this tutorial, we’ll discuss three memory-related concepts in the operating system: private bytes, virtual bytes, and working sets.
- We’ll delve into strategies for monitoring and optimizing the working set to maintain system efficiency and responsiveness.
- Here is my go at an easy-to-understand explanation. A process working set is the amount of physical RAM it is currently using (referencing), in total, to do its work.

- To create a Working Set, you can click the small downward arrow in the upper right corner of the Navigator view and go to 'Select Working Set...'

The "working set" is short hand for "parts of memory that the current algorithm is using" and is determined by which parts of memory the CPU just happens to access. It is totally automatic to you. If you are processing an array and storing the results in a table, the array and the table are your working set.This is discussed because the CPU will automatically store accessed memory in cache, close to the processor. The working set is a nice way to describe the memory you want stored. If it is small enough, it can all fit in the cache and your algorithm will run very fast. On the OS level, the kernel has to tell the CPU where to find the physical memory your application is using (resolving virtual addresses) every time you access a new page (typically 4k in size) so also you want to avoid that hit as much as possible. See What Every Programmer Should Know About Memory - PDF for graphs of algorithm performance vs size of working set (around page 23) and lots of other interesting info.Basically - write your code to access the smallest amount of memory possible (i.e classes are small, not too many of them), and try to ensure tight loops run on a very very small subset of that memory.
