　　Mutex测试

以下是引用片段：
NinGoo:/u01/sysbench/bin>$sysbench --test=mutex --num-threads=16 \
--mutex-num=1024 --mutex-locks=10000 --mutex-loops=5000 run
sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 16

Doing mutex performance test
Threads started!
Done.

Test execution summary:
    total time:                          1.1561s
    total number of events:              16
    total time taken by event execution: 18.3831
    per-request statistics:
         min:                               1084.60ms
         avg:                               1148.94ms
         max:                               1153.52ms
         approx.  95 percentile:         10000000.00ms

Threads fairness:
    events (avg/stddev):           1.0000/0.00
    execution time (avg/stddev):   1.1489/0.02

　　内存测试

以下是引用片段：
NinGoo:/u01/sysbench/bin>$sysbench --test=memory --num-threads=16 \
--memory-block-size=8192 --memory-total-size=1G run
sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 16

Doing memory operations speed test
Memory block size: 8K

Memory transfer size: 1024M

Memory operations type: write
Memory scope type: global
Threads started!
WARNING: Operation time (0.000000) is less than minimal counted value, counting as 1.000000
WARNING: Percentile statistics will be inaccurate
Done.

Operations performed: 131072 (114162.68 ops/sec)

1024.00 MB transferred (891.90 MB/sec)

Test execution summary:
    total time:                          1.1481s
    total number of events:              131072
    total time taken by event execution: 16.0448
    per-request statistics:
         min:                                  0.00ms
         avg:                                  0.12ms
         max:                                  3.60ms
         approx.  95 percentile:               0.01ms

Threads fairness:
    events (avg/stddev):           8192.0000/192.89
    execution time (avg/stddev):   1.0028/0.00
