-bs=4k 表示单次I/O的块文件大小为4KB。默认大小也是4KB。
测试IOPS时，建议将bs设置为一个较小的值，如4k。
测试吞吐量时，建议将bs设置为一个较大的值，如1024k。
-size=1G 表示测试文件大小为1GiB。
-numjobs=1 表示测试线程数为1。
-runtime=1000 表示测试时间为1000秒。如果未配置，则持续将前述-size指定大小的文件，以每次-bs值为分块大小写完。
-group_reporting 表示测试结果里汇总每个进程的统计信息，而非以不同job汇总展示信息。
-filename=iotest 指定测试文件的名称，例如iotest。
-name=Rand_Write_Testing 表示测试任务名称为Rand_Write_Testing，可以随意设定。
