Last time I did something like this I messed with the blocking but the
biggest boost I got was from running chunks of the conversion in parallel.
I'm not sure if it is an option for you but I just divided the table I was
converting into chunks by record number and ran multiple jobs in parallel.

I have a conversion program that will end up writing over 300M 72byte
records and I’m getting pressure to figure out if there is a way to speed
it up. Currently the program is using an F-spec. There are no logicals
over the file and even though there is a unique key, there is no way one
could happen during conversion so I'm not checking or monitoring for one.

Would changing to SQL help in any way?
Can I change something related to the blocking? I’ve never messed with
blocking because the system does it automagically and I always figured it
knew more than me.
Are there other options that I might not have thought about…and no,
writing less records is not an option. 😊
