Re: journalling overhead

As Al stated, no not on a read. Reads are not journaled and not able to be
journaled prior to V5.

Are you sure you're not reading for update and updating? Are you sure you're
not reading for update and there are lock issues? Has an index changed? Have
you put the job in debug and checked for index issues?

Next, an interactive program that reads 200,000 records is, IMO _not_ an
interactive job, it's a batch job running in the interactive environment.
