Hi -Apologize for my insistance, but would it be possible to help on the stats caching? This seriously decreases performances with small files readings!I am volunteer to try to deal with stats caching by myself but I would appreciate some guidance in order to know where I could interact in the code for.
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, -- Olivier
