If that's truly the case then the data=journal mount option should be
removed and the man page updated to reflect this, especially given that
this is supposed to be the safest EXT3 journaling mode, with all data
being written to the journal before being written to the live filesystem.

It's been clear since the beginning of the thread that the OP doesn't
need more performance. More safety possibly, but not more performance.
Which is why I mentioned he "might" want to use data=journal.
