Connection Pool Sizing Calculator
Requests/sec and average query time, via Little's Law, turned into a recommended pool size - not a guess from a config template.
2 connections
Theoretical minimum: 1.0
Based on Little's Law (L = λW): connections needed = arrival rate × time per connection, then padded to your target utilization so you're not running the pool at the ragged edge.
