Slow performance. So we have a few Spring Boot based webapps which were running (along with PgSQL) on a shared AWS t2.medium instance, we migrated these to a GKE cluster with a node pool of e2-standard-2 instances. The nodes are on a private network and don't have public IPs. The services are exposed via Load Balancer based Ingress (with SSL). Even after allocating one core to PgSQL and 2GB RAM, the API calls from the GKE applications are perceptively slower than that of the shared AWS t2.medium instance based deployment. Tried giving generous CPU and RAM to the applications however, it still didn't improve the response time. Since these are the very fist applications being moved to this cluster, there isn't much else running on this cluster. Now sure what's causing the slowness. Have any of you experienced something like this in GKE?
