Well, inode location in reiser4 changed comparing to reiserfs. reiser4 groups inodes of files of one directory together (reiserfs did not do that), but still allocated disk space for inodes dynamically as reiserfs. So, I guess that reiser4 will be better than reiserfs, but still worse than ext[23]. Would you verify this guess it please? > > Thanks, > > Grzegorz Kulewski > >
