nginx_slowfs_cache

[jb]

At least in my experience unless your most used static files exceed in size
your available RAM, or are changing, they are effectively cached by the OS
anyway.

So storing them on a ram disk is really doing the same or worse job than
just letting the OS store them and serve them from its file cache memory
pages. Plus the OS has the advantage of knowing which are less frequently
used and can be purged.
