Pillars of Performance Testing – PSAR
summary
Defines PSAR as Performance Scalability Availability Reliability and uses Apdex score to measure performance, CPU/memory and RDS metrics for resource analysis. Sets up isolated PSR environments, runs single‑user heavy‑data tests versus multiuser load tests, and categorizes root causes as API, SQL, data, or resource limits. Builds Python utilities to generate large test datasets, tunes Spark/EMR configs, and runs a POC that migrated RDS from Graviton to Intel to prove cost and availability gains.
