Dasol Kim updated KAFKA-4971: ----------------------------- Description: I installed OS and kafka in the two SSD and two HDDs to perform the kafka benchmark test based on the disc difference. As expected, the SSD should show faster results, but according to my experimental results, there is no big difference between SSD and HDD. why? Ohter settings have been set to default. *test settings zookeeper node : 1, producer node : 2, broker node : 2(SSD 1, HDD 1) test scenario : Two producers send messages to the broker and compare the throughtput per second of kafka installed on SSD and kafka on HDD command : ./bin/kafka-producer-perf-test.sh --num-records 1000000 --record-size 2000 --topic test --throughput 100000 --producer-props bootstrap.servers=SN02:9092 was: I installed OS and kafka in the two SSD and two HDDs to perform the kafka benchmark test based on the disc difference.
