+## Performance Benchmark
+This tool is used test to following metrics.
+1. publish latency: the time of completing producer data request
+2. E2E latency: the time for a record to travel through Kafka
+3. input rate: sum of consumer inputs in MByte per second
+4. output rate: sum of producer outputs in MByte per second
+
+Run the benchmark from source
+```shell
+./gradlew run --args="Performance --bootstrap.servers localhost:9092 --topic topic --topicConfig partitions:10,replicationFactor:3 --producers 5 --consumers 1 --records 100000 --recordSize 10000"
+```
+### Performance Benchmark Configurations
+1. --bootstrap.servers: the server to connect to
+2. --topic: the topic name
+3. --partitions: topic config when creating new topic. Default: 1 
+4. --replicas: topic config when creating new topic. Default: 1
+5. --consumers: the number of consumers (threads). Default: 1
+6. --records: the total number of records sent by the producers. Default: 1000
+7. --record.size: the record size in byte. Default: 1024 byte
+

 ## Topic Explorer
 
 This tool can expose both earliest offset and latest offset for all (public and private) topics.
