Save your disk, write files directly into RAM with /dev/shm

10 months ago

/dev/shm is a RAM-based scratchpad available in Unix systems by default.
It is a tmpfs filesystem, meaning data stored in /dev/shm is lost upon reboot.
Using /dev/shm can significantly improve performance for file operations by leveraging RAM speed.
It is useful for temporary files, especially when working with large datasets or frequent read/write operations.
Example use cases include linguistics data processing, where files can be accessed much faster.
Tools like jq, rg, and grep benefit from the speedup when files are stored in /dev/shm.
Memory usage should be monitored, as /dev/shm consumes RAM.
