Unless you designed your batch job to run multiple parallel threads, then it
will probably just use 1 of the CPUs, even on a 16 CPU server. It's known a CPU
affinity. So your question probably comes down to how much faster the new CPUs
are.

Subject: Database I/O throughput speeds

Hi,

Can any one give me some ball-park figures for number of I/O operations
(chain, update, write, delete) that can be achieved (per second or per
minute) in an RPG program running in batch mode (priority 50) on a high end
newer model? I am not sure what model my company is going for, but it is
supposed to have 16 CPUs (if I heard it right). I realize that the
throughput may vary based on the other usage of the system, but I would have
something to go by.

I am trying to gauge the impact of adding a few I/O operations to every
transaction when processing a batch of 1-2 million transactions. Our
development machine has nowhere near that power, so running a sample program
on it would not tell me much.

Thanks
Vinay
