URL: https://issues.apache.org/jira/browse/KAFKA-4971
Project: Kafka
Issue Type: Test
Affects Versions: 0.10.0.0
Environment: Oracle VM VirtualBox
OS : CentOs 7

Disk : 8GB
Reporter: Dasol Kim
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
