How Many Concurrent Claude API Requests Can You Actually Hold? Sizing Production Infrastructure with Little's Law and Measured Memory

Concurrency, queue depth, and memory are numbers you can derive, not guess. A working method for sizing Claude API production deployments with Little's Law, a memory probe, and a 30-minute load check — learned the hard way from an OOM crash.
