Is it possible to find all files with a given inode? Efficiently?

Question

It is possible to find all the paths to a file with a given inode, in general, using find's -inum option. But this has awful performance for typical filesystems. What options are there to improve performance?

Are there filesystems with special support for this task? Are there updatedb-like utilities that index inodes?

The more general, the better the answer.
