When we first launched the i3 instances, i3.metals weren't available. We've been wanting to do experiments with i3.metals, but we've been unable to get confirmation that our reservations will transfer over. Until we know that we'll be able to transfer the reservations, there isn't any reason for us to do experiments.

Since you work at Amazon, do you have a sense of big of a difference there is in performance between i3 and i3.metal for database workloads like Postgres?
