Measuring the speed of distribution of configurations

Hi there!

Please tell me how best to measure the speed of distribution of DestinationRule, Service, ServiceEntry, EnvoyFilter, VirtualService configurations. We use oc exec -c istio-proxy --curl localhost:15000/config_dump and then we look for the config name and the last_updated field next to the name. We compare the received time with the time of creating the config for understanding the speed of distribution. Maybe there is an easier way to measure the speed of sending configurations?
