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,
