It would still be slow, but at least with ReiserFS it wouldn't be that
bad, as it handles small files well (packing several to a disk block).
You can also even specify affiliation so that all the attribute "files"
are near the main file (I think it's done by tweaking a hash function
so that the ones you want nearby are nearby in the hash codes, and that
somehow is related to allocation - but I'm not sure).
