If you are running with a kernel that understands htree indexes you only
need to do it once (the kernel will keep the directory up-to-date after
that). If you run with a non-htree kernel then you _should_ do it
afterwards, but it is only really needed if you have added files to an
previously-indexed directory.
"e2fsck -D" will also pack an existing directory, so if you created a
huge directory and deleted all of the files, then you can get a little
bit of space back by re-indexing that directory, but it's not a big
deal in most cases ("mkdir newdir; mv olddir/* newdir; rmdir olddir"
will also do this for you without unmounting the filesystem).
Cheers, Andreas
