Yep. The main drawbacks to a large journal is that (a) they can pin a
lot of buffers in memory at once, and (b) they take longer to recover.
The only advantage of a large journal is that it gives the filesystem
more flexibility in writing things back to the main disk, but it's not
a large effect unless you have a very heavy write load.
