tmpfs is a temporary in-memory file system used in Linux to store files directly in RAM instead of on disk. It is designed for fast read/write operations, making it an ideal choice for storing runtime data, temporary files, and volatile information that does not need to persist after reboot. In a Linux server environment, understanding how tmpfs works is essential for optimizing performance, reducing I/O load, and improving overall system efficiency. How tmpfs Works When you create a tmpfs mount, Linux allocates storage in RAM (and swap, if available). Unlike traditional disk-based file systems, tmpfs dynamically grows and shrinks based…
