> I've been scratching my head about this one for some time. This is an RPG400 program. I have a subfile that is loaded from a file that only contains 3200 records. The initial load takes a long time (over a minute). In subsequent calls to the same program, it responds much better (2-3 seconds). I've gone into debug - doesn't seem to hang at any location. I've watched it process (WRKACTJOB) and it seems to do the same process. I have looked at locked records - doesn't seem to be a problem. Can anyone suggest other techniques for debugging this problem. As you can imagine, the users don't like the long delay.
