Hi George,
Is Elasticsearch and Kibana running on local hardware you have? Or is some or all of it in the Cloud? It seems very strange that your 3 different visualizations would all take 25277ms +/- 1ms while the number of hits are orders of magnitude different in size. It really seems like there's some large latency (about 25 seconds) introduced somewhere.
I'm thinking it might help to turn on the slow log on your data index (looks like it might be packetbeat-*). Can you try to follow the steps here;

Thanks,
Lee
Also, any load balancers or proxies anywhere between your browser, Kibana, and Elasticsearch?
