Answer
Use async communication, caching, stateless services, monitoring, circuit breakers, retries, and backpressure handling.
Quick Answer
Microservices performance best practices: async I/O everywhere, connection pooling, distributed caching (Redis) for hot data, efficient serialization (protobuf instead of JSON for internal APIs), database indexing and query optimization, avoid chatty APIs (aggregate data to reduce round trips), right-size service granularity (too fine-grained = too much network overhead).
