Deletion of ingress, kongplugin crd, how much time ingress controller take to reflect the change on kong?

I have created and deleted ingress and kong plugin crd? After deletion, it’s been 5 minutes and Ican still see the entries in GET /services, GET /plugins api? How much time does it take to reflect the change?

After 10 mins, restarted the pod manually. After restart, I could see that deletion is reflected,

Kong 2.0 and kong ingress controller 0.9.1.
