The current rate limit default maximizes the number of calls we can make in the first 10 minutes, but the larger initial bucket size means we have to drop the per-second token burst. As a result, any process longer than 10 minutes is going to see unnecessary rate limiting by ~100 calls per minute.
This change swaps the large initial bucket for a smaller one, and a larger token burst to increase throughput across long runtimes.
