So Jonathan, you have a concern about the on-disk space efficiency for small file (more or less subsector). It is a problem that we can throw rust at. I am not sure if this is the basis of Claude's concern though. Creating small files, last week I did a small test. With ZFS I can create 4600

Roch what's the minimum allocation size for a file in zfs? I get 1024B by my calculation (1 x 512B block allocation (minimum) + 1 x 512B inode/ znode allocation) since we never pack file data in the inode/znode. Is this a problem? Only if you're trying to pack a lot files small byte
