Detailed Explanation
Lots of benchmark tools are available as described in this post
- IOPS : I/O operations per second
- Throughput or Bandwidth : the amount of data transferred per second
- Latency : the time required to perform an I/O operation
hdparm is a tool for collecting and manipulating the low-level parameters of SATA/PATA/SAS and older IDE storage devices. It also contains a benchmark mode we can invoke with the -t flag, even on a disk with mounted partitions:
$ sudo hdparm -t /dev/nvme0n1
/dev/nvme0n1:
Timing buffered disk reads: 10014 MB in 3.00 seconds = 3337.66 MB/sec
*** the disk read output means how fast the disk can sustain sequential data reads without any filesystem overhead and without prior caching since hdparm automatically flushes it
Using dd for disk performance tests is not recommended. Because dd will perform a sequential write what is not a real scenario, To evaluate your servers, use fio or bonnie++ for performance tests.
Phoronix Test Suite is a complete benchmark suite that curates loads of Linux benchmark. this post provides good instruction for Unbuntu user.
here is short instruction to use Phoronix GIT
#step 1, make sure you have php engine on your system
$sudo apt-get install php-cli php-xml
#step 2, clone phoronix git to get latest version
$ git clone https://github.com/phoronix-test-suite/phoronix-test-suite.git
# Check available test suites
$ cd phoronix-test-suite
$ ./phoronix-test-suite list-available-suites
Best Practices
- 최신 버전 사용 권장
- 공식 문서 참고
- 테스트 환경에서 먼저 검증
