Quite possibly...

But remember, at this point it's unlikely anybody is turning on journaling
for the first time...

So really, if you were to turn off journaling your 1hr batch job might run
in 20-30min.

But are you really going to turn it off to see? So either run the
tools...or turn it on and try it free for 70 days...

Rob was impressed :)

Charles,

you are really telling (and believing) a batch application running 1 h
without journal will take 3 h, if you would start journaling for the
files??? I've never seen any numbers in this range within 20 years!!!
