File I/O or SQL? If SQL, run your SQL statements through Visual Explain.
There is a program trace utility from IBM. I am trying to find out what the name is. Maybe somebody else knows. .

Subject: Profiling RPGLE programs
I have a request from a sister division to look at (and, hopefully
improve) a program that is VERY long running - like 2 days long.
My first thought was I need to know the hot spots in the program but,
in all my years on this platform, I've never needed to profile a program.
Does anyone have any tips, a simple cheat sheet, or primer on the
steps involved?
Thanks!
