I know sharing ChatGPT/GPT/AI generated text in comments here can be unappealing, but I would like to share this one as I feel that I managed to get ChatGPT-4 to summarize this article using a non-computer analogy pretty well: "Imagine you work in a library where you store books on shelves. Your primary task is to take new books and put them on the shelves (write-only load). You don't expect to read the books often, so the number of times you need to open and read the books should be minimal. One day, you notice that several books are being opened and read more often than expected, even though your main task is to put away new books. This is confusing and unexpected, so you start investigating why this is happening. After some investigation, you find out that the library assistant (the operating system) is trying to be helpful by anticipating which books might be needed next and opening them ahead of time (readahead). This anticipation works well when there is plenty of shelf space (memory) available. However, when the library gets crowded (memory pressure), the assistant starts anticipating the wrong books, causing unnecessary book openings (phantom reads). To resolve this issue, you tell the library assistant to stop anticipating which books to open (disabling readahead) when you're just putting away new books. This solves the problem and reduces the number of unnecessary book openings. The experience teaches you the importance of understanding how the library assistant works and shows that addressing unexpected issues can lead to improvements in the overall library system."
