Slowfs cache

hi, anyone using/tried slowfs_cache?

http://labs.frickle.com/nginx_ngx_slowfs_cache/

If I have a machine with big memory, e.g. 128G or more, is it useful to
create a ramdisk and use slowfs cache? or I can just rely on linux VFS
to
reduce disk i/o?

I don’t see the point in the slowfs_cache module, does it actually offer
anything over having nginx configured as reverse caching proxy with the
caching location using the fast disk subsystem and proxy backend reading
from the slow disk subsystem?
