Ben,
May I ask, why turn off 'auto-rearrange content'? Is it not
compatible
with 'use lazy fetching'? Or does
'auto-rearrange content' on its own degrade performance somehow?
auto-rearrange content is very expensive. Preserve selection can also
be expensive, although not nearly as bad. But if we're talking about
a million object table view (which is a little odd, btw, most UIs have
"... and more" instead) then extraneous layout options will add up fast.
I have a vague and hazy memory that auto-rearrange content is not
compatible with use lazy fetching. If you run into trouble, file a
bug, and disable auto-rearrange content as a workaround.
