I haven't tried to profile myself but making a big document updates is
intuitively quicker: it will cause less document repaints. This
performance benefits is expected independently of hardware/platform,
but naturally it will be noticed whenever there's a bottleneck (in
this case, apparently the display export).

I'm convinced you'll find related posts within the mailing list archives. ;-)
