A non-journaling filesystem? Really? Can you explain why you would make
that performance trade-off?
One bit of data here:

I was specifically thinking of linux, where I found that ext3 filesystems
were substantially slower than ext2fs when you are dealing with data being
written out (checkpoints, etc). BDB is doing its own checkpointing via its
log.* files, there's no need for the extra overhead the journaling
filesystem adds.
