　　线程测试

以下是引用片段：
NinGoo:/u01/sysbench/bin>$sysbench --test=threads --num-threads=64 --thread-yields=100 \
--thread-locks=2 run
sysbench 0.4.12:  multi-threaded system evaluation benchmark

Running the test with following options:
Number of threads: 64

Doing thread subsystem performance test
Thread yields per test: 100 Locks used: 2
Threads started!
Done.

Test execution summary:
    total time:                          4.3925s
    total number of events:              10000
    total time taken by event execution: 280.4418
    per-request statistics:
         min:                                  0.04ms

　　文件IO性能测试

　　首先生成需要的测试文件，文件总大小300M，16个并发线程，随机读写模式。执行完后会在当前目录下生成一堆小文件。

以下是引用片段：
NinGoo:/u01/sysbench/bin>$sysbench --test=fileio --num-threads=16 \
--file-total-size=300M --file-test-mode=rndrw prepare

300Mb total file size
Block size 16Kb
Number of random requests for random IO: 10000
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 r/w test
