  • @muru that's a different question, it's asking about the `buffers` part (seen nowadays in `free -w`), it's explicitly excluding the `cache` part. I'm not sure we have an existing Q&A that covers this specifically and clearly. I think we often tend to point people to http://linuxatemyram.com , that's a pretty accurate and well explained answer to the question. – sourcejedi Aug 02 '19 at 08:30
  • I might be biased, but if we insist on closing this question as a duplicate, I think the answer on this question would be better: [The remaining question is when will Linux clean up disk caching and will it at all?](https://unix.stackexchange.com/a/451292/29483) – sourcejedi Aug 02 '19 at 08:37
