Well, as far as I understand the problem is rather that folders on the 
path of the targeted file are not cached at all by io-cache. This is why 
accessing a file makes (quite a lot) network traffic and can introduce 
bottlenecks because each folder is stated on the servers before 
delivering the file, even if that file is indeed cached by io-cache.

I'm still trying to figure out how I can get this cached as well and 
will appreciate any pointers.

Thanks and best regards,
