三、sysbench使用
1、CPU性能测试

cpu性能测试：找范围内最大素数{时间越短越好}

cpu性能测试主要是根据素数的加法运算，这里指定最大素数(质数)为80000，--num-threads=`grep "processor" /proc/cpuinfo | wc -l`指定线程数，默认是1

/usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run

点击(此处)折叠或打开

1. [root@db_test ~]# /usr/local/sysbench/bin/sysbench --test=cpu --cpu-max-prime=80000 run

2. WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

3. sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)

5. Running the test with following options:

6. Number of threads: 1

7. Initializing random number generator from current time

10. Prime numbers limit: 80000

12. Initializing worker threads...

14. Threads started!

17. General statistics:

18. total time:                          10.0057s

19. total number of events:              520

21. Latency (ms):

22. min:                                 18.74

23. avg:                                 19.24

24. max:                                 19.39

25. 95th percentile:                     19.29

26. sum:                              10005.32

28. Threads fairness:

29. events (avg/stddev):           520.0000/0.00

30. execution time (avg/stddev):   10.0053/0.00

实际环境CPU拷机压测脚本如下：

echo -e "进行CPU压力测试: 寻找小于1千万的最大质数,并发线程数10,最大请求数100 "

/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=cpu --debug --cpu-max-prime=10000000 run

2、内存性能测试

sysbench 测试memory的时候是顺序读或写内存的。根据选项的不同，每次操作过程中，每个线程可以获取global或本地的数据块

内存：以不同块大小传输一定数量的数据吞吐量大小{越大越好}

点击(此处)折叠或打开

1. [root@db_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory  help

2. WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

3. sysbench 1.0.3 (using bundled LuaJIT 2.1.0-beta2)

5. memory options:

6.   --memory-block-size=SIZE size of memory block for test [1K]  测试时内存块大小

7.   --memory-total-size=SIZE total size of data to transfer [100G] 传输数据总大小

8.   --memory-scope=STRING       memory access scope {global,local} [global]  内存访问范围

9.   --memory-hugetlb[=on|off] allocate memory from HugeTLB pool [off] 从 HugeTLB pool内存分配

10.   --memory-oper=STRING type of memory operations {read, write, none} [write] 内存操作类型

11.   --memory-access-mode=STRING memory access mode {seq,rnd} [seq] 存储器存取方式

示例：测试传输数据总量为5G，每个块大小是1K（一般设置是8K），连续读写的情况下，吞吐量3435.87 MiB/sec
[root@db_test fileio]# /usr/local/sysbench/bin/sysbench --test=memory --memory-block-size=1K --memory-total-size=5G run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.

General statistics:
    total time:                          1.4883s
    total number of events:              5242880

    execution time (avg/stddev):   0.6310/0.00

实际内存压力测试脚本：

/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=memory --memory-block-size=8K --memory-total-size=${MEM}G --memory-oper=read run

echo -e "进行内存压力测试: 测试范围32G,并发线程数10,最大请求数100, 写 "

/usr/local/bin/sysbench --num-threads=10 --max-requests=100 --test=memory --memory-block-size=8K --memory-total-size=${MEM}G --memory-oper=write run
