sysbench除了测试mysql，还可以测试很多东西。
比如：cpu。
cpu-max-prime：素数生成数量的上限。
[root@localhost ~]# sysbench --test=cpu --cpu-max-prime=20000 --num-threads=4 run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
WARNING: --num-threads is deprecated, use --threads instead
sysbench 1.0.17 (using bundled LuaJIT 2.1.0-beta2)
Running the test with following options:
Number of threads: 4
Initializing random number generator from current time
Prime numbers limit: 20000
Initializing worker threads...
Threads started!
CPU speed:
events per second: 1702.29
General statistics:
total time: 10.0020s
total number of events: 17029
Latency (ms):
min: 2.17
avg: 2.35
max: 4.37
95th percentile: 2.71
sum: 39991.72
Threads fairness:
events (avg/stddev): 4257.2500/14.43
execution time (avg/stddev): 9.9979/0.00
测试io。
准备2g的数据。
sysbench --test=fileio --file-total-size=2G prepare
--file-test-mode 还可以为
seqwr：顺序写入
seqrewq：顺序重写
seqrd：顺序读取
rndrd：随机读取
rndwr：随机写入
rndrw：混合随机读写
测试随机读。
Throughput: 吞吐量
read, MiB/s: 185.54 每秒184m
[root@localhost ~]# sysbench --test=fileio --file-total-size=2G --file-test-mode=rndrd run
WARNING: the --test option is deprecated. You can pass a script name or path on the command line without any options.
sysbench 1.0.17 (using bundled LuaJIT 2.1.0-beta2)
Running the test with following options:
Number of threads: 1
Initializing random number generator from current time
Extra file open flags: (none)
128 files, 16MiB each
2GiB total file size
Block size 16KiB
Number of IO requests: 0
Read/Write ratio for combined random IO test: 1.50
Periodic FSYNC enabled, calling fsync() each 100 requests.
Calling fsync() at the end of test, Enabled.
Using synchronous I/O mode
Doing random read test
Initializing worker threads...

测试顺序读。
可以看到，顺序读的性能几乎是随机读的10倍。
