 - **Protobuf vs. Java**: Protobuf is **77x faster** and **10x smaller** than standard Java serialization.
 - **Binary vs. Text**: Kryo (Binary) provides **6x higher throughput** than JSON (Text) for complex objects due to Varint compression and omission of field names.
 
+#### 5.3 End-to-End Load Test (Business Simulation)
+
+Use `LoadTestApp` to simulate microservice-style calls with configurable concurrency, duration, payload size, and output file. It reports QPS, P50/P95/P99 latency, error rate, and basic GC/heap stats.
+
+**1) Build**
+
+```bash
+mvn -pl rpc-consumer -am -DskipTests package
+```
+
+**2) Start Provider**
+
+```bash
