The authors connect local performance tests to architectural models to estimate system effects. They compare original and updated component timings, propagate meaningful deviations through a dependency graph, and update a Queueing Petri Net model. Across two microservice benchmarks with injected busy-wait slowdowns, the approach detected seven of nine notable response-time regressions; both misses had small observed effects.
