Re: Subfile initial load very slow

Huh. I've used load-all subfiles for years, and whilst they may not be the
most efficient (compared to page-at-a-time or extensible, for instance),
I've never seen the kind of 'first-time-only' problems that he's
experiencing. If it's slow, it's always slow. And frankly, with 3200
records, I'd expect a few seconds to laod at max. My guess is that it's a
logical that's being rebuilt or something similar.

Luckily, the fact that it takes so long means that he has the opportunity to
check it out. What I would do is as follows:

1. Open 2 green-screen sessions (jobs)
2. In job 1, call the program
3. In job 2, do a WRKJOB on job 2. Check out options 14 (Open files), 15
(File overrides) and 11 (Call stack). With option 14, use F11 (Display I/O
details) and press F5 repeatedly. With option 11, use F10 repeatedly to see
what procedure is being called.

You might need to do the above processing several times (ending job 1
between runs, so it's always the first-time through). Perhaps he will find
out that there is some sort of low-level file processing going on which is
slowing things down.

Sounds like one of the top two answers to me as well. The other top answer
is to just load one page at a time and let the subfile expand as the user
presses page down. Neither are very hard to do. Not to be confused with
"Page at a Time" which Gary proposed but rightly said was a big change.
Page at a time does not use an extensible subfile which the OP already said
he has. Sounds like he is loading the whole subfile all at once.
