I suspect that is what he's seen.
From my experience, ext3 is only a percent or two slower than ext2 under pg_bench. It saves an amazing amount of time
onstartup after a failure by not having to fsck to confirm that the filesystem is in a consistent state.
I believe that ext3 is a metadata journaling system, and not a data journaling system. This would indicate that the PG
transactioningis complimentary to the filesystem journaling, not duplication.
