Hi guyz, I have the exact same problem. If I deploy the service as LB, it is blazing fast, but if I use the basic ingress on Google Ingress, I have random latency whith response time ranging from 50ms to 5s. -- You received this message because you are subscribed to the Google Groups "Kubernetes user discussion and Q&A" group.
