Increasing the journal size may speed up certain filesystem workloads
which are causing the journal to wrap very frequently.  However,
increasing the journal *will* increase the time to replay the journal....

How long did the journal replay take when you were using the 128MB
internal inode?  Was the 800 seconds to replay for the the case when
you were using the internal journal or the external journal?
