------------------------------
Description:
When using TestDFSIO to compare the random read performance of HDFS and Ozone,
Ozone is way more slow than HDFS. Here are the data,
||Random read||Round1||Round2||
|HDFS|----- TestDFSIO ----- : random read
Number of files: 64
Total MBytes processed: 65562.04
Throughput mb/sec: 101.72
Average IO rate mb/sec: 111.12
IO rate std deviation: 36.39
Test exec time sec: 47.06|----- TestDFSIO ----- : random read
Number of files: 64
Total MBytes processed: 65561.07
Throughput mb/sec: 72.52
Average IO rate mb/sec: 89.14
IO rate std deviation: 46.83
Test exec time sec: 49.5|
|Ozone|----- TestDFSIO ----- : random read
Number of files: 64
Total MBytes processed: 65561.35
Throughput mb/sec: 19.59
Average IO rate mb/sec: 27.69
IO rate std deviation: 18.8
Test exec time sec: 147.31|----- TestDFSIO ----- : random read
Number of files: 64
Total MBytes processed: 65560.12
Throughput mb/sec: 22
Average IO rate mb/sec: 29.39
