The document discusses five tips for improving performance of microservices built with Quarkus, a Kubernetes-native Java framework. The tips are to tailor logs and profiles, use variables for customization and default values, use Micrometer in tests to measure endpoint performance, ease upgrades by using commands to add extensions to build tools, and compare REST, GraphQL and gRPC for service-to-service communication efficiency.
