performancewhile
Performancewhile is a term used in software performance engineering to describe an approach for evaluating how a system maintains its performance while handling varying workloads. The concept emphasizes sustaining target levels of throughput and response time during multitasking or scale events, rather than focusing solely on peak performance under fixed conditions.
Origin and usage: The term emerged in practitioner circles in the 2010s as a shorthand for examining
Core concepts: It centers on measuring key metrics such as throughput, latency distribution (especially p95 and
Methodology: Techniques include time-based baselining, continuous profiling, mixed-workload testing, chaos engineering, and autoscaling traces. Observability practices
Applications and relation to related concepts: The concept is often applied to cloud-native microservices, data pipelines,
