If you are putting xfs on a disk and not using it for I/O intensive
operations, then a smaller log is all you need. There is a cost
associated with a larger log - longer mount times even when the
filesystem was cleanly unmounted.
The default size does grow with larger filesystems, but I think they
need to be pretty big before that kicks in. The sizing is more an Irix
thing than a linux one - I think it does not kick in until 1 Tbyte.
