Hello Jan, Sorry for the delay; but reading the thread "Severe performance issues with large directories" I just remembered that the backend has a little bit of a problem with big directories - storage overhead.
Do you see any way to split directories into a series of blocks (like files are done), and when changing only a few of the files using pointers to the unmodified blocks of the old directory? I don't propose a real delta design - that was too slow, IIRC. Just re-use of directory blocks; that shouldn't bring any performance issues. Is there some way to do that? Perhaps multiple "." entries in a directory, which just point to other parts? Regards, Phil
