No, there is not.

Journalling can be very fast when sync writes are required.
(for email, NFS, or whatever) At other times, it can be slow.
Your mileage may vary.

Note that many journalling filesystems have performance
benefits that are completely unrelated to journalling.
This is simply a result of newer design.
