测试:
1)测试CPU: sysbench --test=cpu --cpu-max-prime=2000 run
root@db2:~# sysbench --test=cpu --cpu-max-prime=2000 run
sysbench 0.4.12: multi-threaded system eva luation benchmark
Running the test with following options:
Number of threads: 1
Doing CPU performance benchmark
Threads started!
Done.

execution time (avg/stddev): 3.7041/0.00
2)测试线程：sysbench --test=threads --num-threads=500 --thread-yields=100 --thread-locks=4 run
root@db2:~# sysbench --test=threads --num-threads=500 --thread-yields=100 --thread-locks=4 run

3)测试IO：--num-threads 开启的线程 --file-total-size 总的文件大小
1，prepare阶段，生成需要的测试文件，完成后会在当前目录下生成很多小文件。
sysbench --test=fileio --num-threads=16 --file-total-size=2G --file-test-mode=rndrw prepare
2，run阶段
sysbench --test=fileio --num-threads=20 --file-total-size=2G --file-test-mode=rndrw run
3，清理测试时生成的文件
sysbench --test=fileio --num-threads=20 --file-total-size=2G --file-test-mode=rndrw cleanup
root@db2:~/io# sysbench --test=fileio --num-threads=16 --file-total-size=2G --file-test-mode=rndrw prepare
sysbench 0.4.12: multi-threaded system eva luation benchmark
