sysbench 사용법

sysbench를 활용한 CentOS 7.0 성능 측정하기

1. sysbench 설치

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | bash

yum -y install sysbench

2. 성능 측정, 로그로 남기기

 2.1 cpu : --cpu-max-prime 값이 수행되는데 걸린 시간을 확인

for threads in 1 2 3 4; do

    sysbench --test=cpu --cpu-max-prime=20000  --max-requests=10000 --max-time=100 --num-threads=$threads run >> cpu-sysbench-threads-$threads

        done

 2.2 memory

 # read

sysbench --test=memory --memory-block-size=1K --memory-scope=global --memory-total-size=10G --max-time=100 --memory-oper=read run >> memory-sysbench-read

 # Write

sysbench --test=memory --memory-block-size=1K --memory-scope=global --memory-total-size=10G --max-time=100 --memory-oper=write run >> memory-sysbench-write

 2.3 disk : block size, sequential read, threads

for size in 4k 8k 16k; do

        for mode in seqrd; do

             sysbench --test=fileio --file-num=1 --file-total-size=10G prepare

             for threads in 1 2 4; do

                    sysbench --test=fileio --file-total-size=10G --file-test-mode=$mode\

                         --max-time=60 --max-requests=0 --num-threads=$threads\

                         --file-num=1 --file-block-size=$size run >> fileio-sysbench-size-$size-mode-$mode-threads-$threads.txt

             done

            sysbench --test=fileio --file-total-size=$size cleanup

        done

done
