Is there anyway I can speed up the rate at which the slave replicas will fetch data from master?
I am using bin/kafka-producer-perf-test.sh to test the throughput of my producer. And I have set a client quota of 50 MBps. Now without any replicas I am getting throughput ~ 50MBps but when replication factor is set to 3, it reduces to ~30 MBps. There is no other traffic in the network so I am not sure why things are slowing down. Is there some parameter like replica.socket.receive.buffer.bytes, replica.fetch.min.bytes that needs to be tuned to achieve high throughput? How can I speed up my replicas? Thanks, Archie
