The author investigates discrepancies in RAM reporting tools on FreeBSD, explaining that high 'used' memory often reflects disk caching rather than active process consumption. This cached memory is volatile and automatically reclaimed by the kernel when applications require more resources, a behavior common in modern operating systems like Linux.
Background
Modern operating systems utilize unused RAM to cache disk data to improve performance, which can lead to confusion when monitoring tools report high memory usage.
