Saturation Point
// Definition
The load level at which adding more users no longer increases throughput — a resource (CPU, DB, queue) is fully utilised. Past this point, response times rise sharply while requests per second flatten.

Stress Testing
Pushing the system beyond its limits to find the breaking point and observe failure modes. Asks: where does this fall over, and how does it recover?
Throughput
The amount of work completed per unit of time — requests per second, transactions per second. Higher is better.
Load Testing
Verifying system behaviour under expected production load. Confirms the application meets performance targets at typical concurrent-user counts before release.
