+== Scalability and performance
+
+{ServerlessProductName} has been tested with a configuration of 3 main nodes and 3 worker nodes, each of which has 64 CPUs, 457 GB of memory, and 394 GB of storage each.
+
+The maximum number of Knative services that can be created using this configuration is 3,000. This corresponds to the xref:../../scalability_and_performance/planning-your-environment-according-to-object-maximums.adoc#cluster-maximums-major-releases_object-limits[{product-title} Kubernetes services limit of 10,000], since 1 Knative service creates 3 Kubernetes services.
+
+The average scale from zero response time was approximately 3.4 seconds, with a maximum response time of 8 seconds, and a 99.9th percentile of 4.5 seconds for a simple Quarkus application. These times might vary depending on the application and the runtime of the application.
