I read the article and I really don't understand. Linux already buffers files into RAM if there's any unused, why would you do this?

The "so you wont need to read files from disk" argument is bullshit because tmpfs data can be evicted to swap. If memory pressure is high you will still be reading from disk.

And high memory pressure is also what makes disk-backed /tmp slow. No improvement at all.
