Where does this aversion to small file come from? Why are you all obsessing over it?
Nodes stores what node stores. It’s an engineering challenge knocking to your door to make it fast. Take it. Don’t swipe it under the rug.
I’m for one happy that there are tons of small files. I learned a lot about the filesystem and software I was using. Now my node serves small files much faster then large file (I measured). Yes, I’m not joking. No, it’s not caching. I turned caching off for measurements. And it is not wasting space on partially utilized sectors either. I feel rather good about. And you are trying to hide from it. Weird.
