...Using ext2_inode_scan from libext2fs, read the inode tables of the corresponding block groups in a batch [3]. While scanning the block group, store the block numbers of all directory blocks. Once the scan is complete, sort the directory block numbers and read all the blocks using ext2fs_read_dir_block(). time: 22.7 s data read: 119,900 KB The reasoning behind the last approach is that the bottleneck here are path lookups -- the disk head must move back and forth between the inode table and directory blocks. By reading the inodes and directory blocks in a batch, we should be...
