+
+The Mean Time To Production (MTTP) benchmark measures the time it takes for Flux
+to deploy application changes into production. We measure the time spent on fetching
+app packages from the registry (Flux OCI artifacts and Helm charts) and the time spent
+reconciling app definitions on the Kubernetes cluster.
+
+For this benchmark we assume 100, 500 and 1000 app packages being pushed to the registry at the same time.
