Uh, forgive my ignorance. "journal" means metadata+data journaling. If I have large data movement, how can that be even faster? Ok, I see the facts around sync'ing the fs. But anyway the data size written should be nearly doubled compared to data=ordered. Reiserfs journaling has to be real incredible in comparison to ext3(ordered). I have the impression that large files are hit most.
