Totally depends on terrain and group.
If I think I will eventually need the big ring on current stretch, I will go to it ASAP (once moving about 12MPH). On the other hand if I know next stretch is mostly uphill and/or rollers and I don't think I will need the big ring, I don't bother until I am running out of gears.
