At 300-400K rows I'd suggest skipping model overhead and go to straight arrays, using something like arcreative proposed. You could also use the AR `in_batches` method combined with `pluck` to...

I've done some benchmarking on a 440K row table and the solution from @arcreative is a lot faster than in_batches/pluck with about 700ms vs 5.6s. The naive find_each took 6.8s,...
