hi, anyone using/tried slowfs\_cache?

[http://labs.frickle.com/nginx\_ngx\_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?
