You know I used to think about raw rows, performance, etc., but, after
I just trusted WebObjects and learned to code more for it, we have
never had any performance problems. And in cases where we had some
pretty extensive processing the long response page with decent
progress indicator worked great for the users.
my two cents

What Mike said. Jumping to conclusions is very ineffective
optimization technique. Measure. Log. Investigate. First
determine why it is slow. Look at the database. Can you add
indexes to make it faster? Will a different schema address the
performance problem. Then look at EOF and see if there are built in
ways to handle this, batch faulting is one such example. Failing
that, look at what can be done in code.

Thanks for the input.
I have decided that this whole course is wrong. We have some
performance
problems and my boss wanted to see if there was a magic bullet.
Loading the
whole database into memory at startup was not the way to go.
I think we need to go to raw rows for display only screens and
only make EO
objects when we are going to edit. I think this is the
recommended way to
go.
