RE: Sub files in RPGLE

[boothm@xxxxxxx]

This points out a question I have pondered.  Recently I loaded a subfile where 
I knew the records would be in excess of 3,000 but I was thinking I would load 
it and let it sit there all day, so loading wasn't a real issue.  (I was 
messing about with the green screen scroll bar and was curious about 
performance.)  

Imagine my surprise when the subfile loaded in under 3 seconds.  With that sort 
of performance page at a time can be reserved for truly large files, right?  
But I have wondered if this was typical performance?  What are others seeing?
