负载启动后会启动5个进程，2个后端，3个前端
Test run time = 300 seconds, Warmup = 300 seconds.
Running 5 copies of the test on 1 clients

Op latency reporting activated
Clients have a total of 1024 MiBytes of memory
Clients have 204 MiBytes of memory size per process
Clients each have 5 processes
Adjustable aggregate data set value set to 1024 MiBytes

生成目录如下
drwxr-xr-x. 7 root root 7 Jun 7 10:23 CL0_EDA_BACKEND
drwxr-xr-x. 7 root root 7 Jun 7 10:23 CL1_EDA_BACKEND

drwxr-xr-x. 12 root root 12 Jun 7 10:23 CL4_EDA_FRONTEND
根据Benchmark文件配，每个前端进程创建10个子目录，<override_parm name="DIR_COUNT">10</override_parm>
每个后端进程创建5个子目录，<override_parm name="DIR_COUNT">5</override_parm>

特别说明一下
所有前端目录和后端目录Dir*都会创建名字为buket*的子目录
前端的bucket子目录是26个，后端的bucket子目录是24个

Benchmark配置文件中的每个目录文件数<override_parm name="FILES_PER_DIR">10</override_parm>是指的bucket*子目录的文件数
创建的目录总数
[root@localhost spec]# ls -lR | grep "^d" | wc -l
1065
1065=5+2*(5*24+5)+3*(10*26+10)
创建的文件总数
[root@localhost spec]# ls -lR | grep "^-" | wc -l
9200
9200=2*5*23*10+3*10*23*10
这里的23是每个目录下的子目录数，不是24或26，而是23
创建的总文件大小
