sysbench 压力测试 | 易学教程

sysbench支持以下几种测试模式：
1、CPU运算性能
2、磁盘IO性能
3、调度程序性能
4、内存分配及传输速度
5、POSIX线程性能
6、数据库性能(OLTP基准测试)

--file-total-size=SIZE total size of files to create [2G] #要创建的文件的总大小 [2G]
--file-test-mode=STRING test mode {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw} #测试模式 {seqwr, seqrewr, seqrd, rndrd, rndwr, rndrw}

--file-extra-flags=[LIST,...] list of additional flags to use to open files {sync,dsync,direct} [] #用于打开文件的附加标志列表 {sync,dsync,direct} []
--file-fsync-freq=N do fsync() after this number of requests (0 - don't use fsync()) [100] #执行fsync()函数的频率。fsync主要是同步磁盘文件，因为可能有系统和磁盘缓冲的关系。 0代表不使用fsync函数。默认值为100。
--file-fsync-all[=on|off] do fsync() after each write operation [off] #每执行完一次写操作，就执行一次fsync。默认为off。
--file-fsync-end[=on|off] do fsync() at the end of test [on] #在测试结束时执行fsync函数。默认为on。
--file-fsync-mode=STRING which method to use for synchronization {fsync, fdatasync} [fsync] #文件同步函数的选择，同样是和API相关的参数，由于多个操作系统对于fdatasync支持不同，因此不建议使用fdatasync。默认为fsync。
--file-merged-requests=N merge at most this number of IO requests if possible (0 - don't merge) [0] #大多情况下，合并可能的IO的请求数，默认为0。
--file-rw-ratio=N reads/writes ratio for combined test [1.5] # 测试时的读写比例，默认时为1.5，即可3：2。
